Which type of class is referred to as a superclass?

The term "superclass" refers to a class that is extended or inherited by other classes, which are often called subclasses or child classes. A superclass contains properties and methods that are shared among its subclasses. In this context, "parent class" is a synonymous term for superclass, which emphasizes its role in the inheritance hierarchy.

In object-oriented programming, the parent class provides a foundation for child classes, allowing them to access and utilize the functionality defined in the parent class while also allowing the child classes to have their own unique properties and methods. This relationship promotes code reusability and establishes a clear structure in the design of classes.

The other terms might relate to specific contexts but are not the correct terminology for describing a superclass. For example, "base class" also aligns closely with the concept of superclass; however, in the context of relationships, "parent class" is the most precise answer here. "Child class" refers to the classes that inherit from a superclass, while "intermediate class" is not a standard term used in this context.
