Task: Class Definition Understanding (ontology: Earth_Environment/OBOE)

Which of the following definitions best describes 'PrefixedUnit'?

A. A the concept is the product of at least two base or derived units. For example, 'meter per second square' denotes a the concept defined over 'meter' (a base unit) and 'per second square' (a derived unit).
B. A the concept raises a base or prefixed unit to an integer power other than 0 or 1. For example, the unit 'square meter' is a unit derived from the 'meter' base unit raised to the power 2. As another example, a 'square centimeter' is a unit derived from the 'centimeter' prefixed unit raised to the power 2.

BRL 20160601: I removed this restriction so that CompositeUnits like XXXPerLiter would not reason to owl:Nothing. hasUnit exactly 1 (BaseUnit or PrefixedUnit)
C. A the concept is a unit that is not naturally decomposed into other units.
D. A prefixed unit consists of a base unit and a prefix integer value that serves as a multiplier. For example, a centimeter is a prefixed unit that combines a meter base unit and the prefix multiplier 0.01 such that one centimeter is equivalent to 0.01 meters.

Answer: A prefixed unit consists of a base unit and a prefix integer value that serves as a multiplier. For example, a centimeter is a prefixed unit that combines a meter base unit and the prefix multiplier 0.01 such that one centimeter is equivalent to 0.01 meters.
