Information: - The GNU Project is a free software, mass collaboration project, announced on September 27, 1983, by Richard Stallman at MIT. Its aim is to give computer users freedom and control in their use of their computers and computing devices, by collaboratively developing and providing software that is based on the following freedom rights: users are free to run the software, share it (copy, distribute), study it and modify it. GNU software guarantees these freedom-rights legally (via its license), and is therefore free software; the use of the word "free" always being taken to refer to freedom. - The GNU Core Utilities or coreutils is a package of GNU software containing reimplementations for many of the basic tools , such as cat , ls , and rm , used on Unix - like operating systems . It is a combination of a number of earlier packages , including textutils , shellutils , and fileutils , along with some other miscellaneous utilities . - GNU is an operating system and an extensive collection of computer software. GNU is composed wholly of free software, most of which is licensed under the GNU Project's own GPL. - A Unix-like (sometimes referred to as UN*X or *nix) operating system is one that behaves in a manner similar to a Unix system, while not necessarily conforming to or being certified to any version of the Single UNIX Specification. A Unix-like application is one that behaves like the corresponding Unix command or shell. There is no standard for defining the term, and some difference of opinion is possible as to the degree to which a given operating system or application is "Unix-like". - Unix (trademarked as UNIX) is a family of multitasking, multiuser computer operating systems that derive from the original AT&T Unix, developed starting in the 1970s at the Bell Labs research center by Ken Thompson, Dennis Ritchie, and others.

Information: - Rajiformes is one of the four orders in the superorder Batoidea, flattened cartilaginous fishes related to sharks. Rajiforms are distinguished by the presence of greatly enlarged pectoral fins, which reach as far forward as the sides of the head, with a generally flattened body. The undulatory pectoral fin motion diagnostic to this taxon is known as rajiform locomotion. The eyes and spiracles are located on the upper surface of the head and the gill slits are on the underside of the body. Most species give birth to live young, although some lay eggs with a horny capsule ("mermaid's purse"). - Myliobatiformes is one of the four orders of batoids , cartilaginous fishes related to sharks . They were formerly included in the order Rajiformes , but more recent phylogenetic studies have shown the myliobatiforms to be a monophyletic group , and its more derived members evolved their highly flattened shapes independently of the skates . - In cryptography, SHARK is a block cipher identified as one of the predecessors of Rijndael (the Advanced Encryption Standard). - Spiracles (or ) are openings on the surface of some animals, which usually lead to respiratory systems. After reading the paragraphs above, we are interested in knowing the entity with which 'myliobatiformes' exhibits the relationship of 'instance of'. Find the answer from the choices below.
