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

Which of the following definitions best describes 'Measurement'?

A. A the concept is a derived property of an entity that must be combined with concrete characteristics to be used in a measurement. A qualifier is either a base (atomic) or composite qualifier. As an example, the base qualifier minimum can be combined with a characteristic length to create a minimum length qualified characteristic. A composite qualifer is used to combine multiple qualifiers.
B. A the concept defines a reference for comparing or naming entities via a measurement. A the concept can be defined intentionally (e.g., as in the case of units) or extensionally (by listing the values of the the concept, e.g., for color this might be red, blue, yellow, etc).
C. A the concept is a mapping from a source unit to a target unit via a multiplier and an offset value.
D. A the concept is an assertion that a characteristic of an entity had a particular value with respect to an observation event. A the concept is comprised of a characteristic, a value, a the concept standard, and a protocol. Measurements can also have precision as well as a description of the methods used. Measurements can encapsulate characteristics that were recorded, but not necessarily measured in a physical sense. For example, the name of a location and a taxon can be captured through measurements.
