In the context of definition, the class whose membership is divided into subclasses is called:

Correct option is D

In classification systems, particularly in biology and taxonomy, a Genus is a class whose membership is divided into subclasses or species. A genus is broader than a species and contains several species that share common characteristics.

Information Booster:

1. A Genus contains multiple species that are closely related but distinct from one another.
2. The term Genus is used in biological classification and taxonomy to categorize organisms based on shared traits.
3. Each Genus is divided into several species, which are more specific than the genus.
4. In scientific classification, the genus is ranked above species but below family.
5. The classification hierarchy typically follows: Domain > Kingdom > Phylum > Class > Order > Family > Genus > Species.

Additional Knowledge:

• Species: A species is the most specific classification in taxonomy, referring to organisms that can interbreed and produce fertile offspring. It is not used for dividing classes into subclasses.
• Set: A set is a well-defined collection of distinct objects, but it does not refer to a class divided into subclasses.
• Group: A group refers to a collection of entities that are associated with each other in some manner, such as in mathematics or social contexts, but it does not relate to the division of classes into subclasses.
