Question: Which Macintosh portable computer that has been available since 2008 is abbreviated MBP?

Context paragraphs:
Hyperion (computer): The Hyperion is an early portable computer that vied with the Compaq Portable to be the first portable IBM PC compatible.  It was marketed by Infotech Cie of Ottawa, a subsidiary of Bytec Management Corp., who acquired the designer and manufacturer Dynalogic in January 1983.  In 1984 the design was licensed by Commodore International in a move that was forecast as a "radical shift of position" and a signal that Commodore would soon dominate the PC compatible market.  Despite computers being "hand-assembled from kits" provided by Bytec and displayed alongside the Commodore 900 at a German trade show as their forthcoming first portable computer, it was never sold by Commodore and some analysts downplayed the pact.  The Hyperion was shipped in January 1983 at C$4995, two months ahead of the Compaq Portable.

PowerBook 100: The PowerBook 100 is a portable subnotebook personal computer that was designed and manufactured by Sony for Apple Computer and introduced on October 21, 1991, at the COMDEX computer expo in Las Vegas, Nevada.  Priced at US$2,300, the PowerBook 100 was the low-end model of the first three simultaneously released PowerBooks. Its CPU and overall speed closely resembled those of its predecessor, the Macintosh Portable.  It had a Motorola 68000 16-megahertz (MHz) processor, 2-8 megabytes (MB) of memory, a 9 in monochrome backlit liquid crystal display (LCD) with 640 × 400 pixel resolution, and the System 7.0.1 operating system.  It did not have a built-in floppy disk drive and was noted for its unique compact design that placed a trackball pointing device in front of the keyboard for ease of use.

Apple Modem: The Apple USB Modem is a combined 56 kbit/s data modem and 14.4 kbit/s fax external USB modem introduced by Apple Inc. after the internal 56k modem was dropped on the October 12, 2005 iMac G5 revision.  While it looks similar, it should not be confused with Apple's optional USB Ethernet Adapter accessory, available for its MacBook Air and MacBook Pro Retina range of laptops since 2008.

Mactracker: Mactracker is a freeware application containing a complete database of all Apple hardware models and software versions, created and actively developed by Ian Page.  The database includes (by no means exhaustive) the Lisa (under its later name, Macintosh XL), Classic Macintosh (1984–1996), printers, scanners, QuickTake digital cameras, iSight, iPod, iPhone, iPad, AirPort, along with all versions of the Classic Mac OS, macOS, and iOS.  For each model of desktop and portable computer, audio clips of the corresponding startup chime or chime of death are also included.

Macintosh Portable: The Macintosh Portable is Apple Inc.'s first battery-powered portable Macintosh personal computer.  Released on September 20, 1989, it was received with excitement from most critics but consumer sales were quite low.  It featured a fast, sharp, and expensive black and white active matrix LCD screen in a hinged design that covered the keyboard when the machine was not in use.  The Portable was one of the early consumer laptops to employ an active matrix panel, and only the most expensive of the initial PowerBook line, the PowerBook 170, used one, due to the high cost.  The cursor pointing function was handled by a built-in trackball that could be removed and located on either side of the keyboard.  It used expensive SRAM in an effort to maximize battery life and to provide an "instant on" low power sleep mode.  The machine was designed to be high-performance, at the cost of price and weight.

MacBook Pro: The MacBook Pro (sometimes abbreviated MBP) is a line of Macintosh portable computers introduced in January 2006 by Apple Inc.  Replacing the PowerBook G4, the MacBook Pro was the second model to be announced during the Apple–Intel transition, after the iMac.  It is the high-end model of the MacBook family and is currently available in 13- and 15-inch screen sizes.  A 17-inch version was available between April 2006 and June 2012.

Apple IIc: The Apple IIc, the fourth model in the Apple II series of personal computers, is Apple Computer’s first endeavor to produce a portable computer.  The result was a 7.5 lb notebook-sized version of the Apple II that could be transported from place to place.  The "c" in the name stood for "compact", referring to the fact it was essentially a complete Apple II computer setup (minus display and power supply) squeezed into a small notebook-sized housing.  While sporting a built-in floppy drive and new rear peripheral expansion ports integrated onto the main logic board, it lacks the internal expansion slots and direct motherboard access of earlier Apple IIs, making it a closed system like the Macintosh.  However, that was the intended direction for this model — a more appliance-like machine, ready to use out of the box, requiring no technical know-how or experience to hook up and therefore attractive to first-time users.

Compaq Portable: The Compaq Portable is an early portable computer which was one of the first 100% IBM PC compatible systems.  It was Compaq Computer Corporation's first product, to be followed by others in the Compaq portable series and later Compaq Deskpro series.

IBM 5100: The IBM 5100 Portable Computer is a portable computer (one of the first) introduced in September 1975, six years before the IBM Personal Computer.  It was the evolution of a prototype called the SCAMP (Special Computer APL Machine Portable) that was developed at the IBM Palo Alto Scientific Center in 1973.  In January 1978 IBM announced the IBM 5110, its larger cousin, and in February 1980 IBM announced the IBM 5120.  The 5100 was withdrawn in March 1982.

Apricot Portable: The Apricot Portable was a computing device manufactured by Apricot Computers, and was released to the public in November 1984.  It was Apricot Computers' first attempt at manufacturing a portable computer, which were gaining popularity at the time.  Compared to other portable computers of its time like the Compaq Portable and the Commodore SX-64, the Apricot Portable was the first computer to have an 80-column and 25-line LCD screen and an input/output speech recognition system.
