Answer:
c. Derived class
Explanation:
Subclass is a term or function that is used in computer or specifically object-oriented programming. The name subclass comes from the fact that the class is obtained from basing a class upon another class through inheritance such that it maintains identical execution.
Therefore, because a subclass is derived from a base class through inheritance, it is often referred to as DERIVED CLASS.
This DERIVED CLASS comprises all the characteristics of the base class often with extra features.
