Question: Base classes are also called

Options:
- derived classes
- subclasses
- class instances
- superclasses

Option 1: 'derived classes' — This term refers to classes that inherit from another class, i.e., they are built from a base class. Describing base classes as derived would be inaccurate because derivation goes from the base to the derived, not vice versa.

Option 2: 'subclasses' — Similar to 'derived classes,' a subclass is a class that inherits from a base class. The base class itself is not called a subclass; instead, it is the source from which subclasses are derived.

Option 3: 'class instances' — An instance (or object) is a concrete realization of a class, not the class itself. The term 'base class' denotes the class definition, not an instance of it.

Option 4: 'superclasses' — This term is used to describe base classes in relation to their derived classes. A superclass is the parent in an inheritance relationship, from which more specialized subclasses inherit. It correctly identifies the base class.

In summary, the other three options describe entities or concepts related to inheritance from a base class, but they are not the terminology for the base class itself. The term that correctly names a base class in this context is the one that denotes a parent in the inheritance hierarchy.
