In OOP, which class is a specialized version of another class?

• A. Child Class
• B. Is-a Class
• C. Base Class
• D. Parent Class

Answer: (A)

In OOP, specialization happens when a new class is built on top of an existing one, inheriting its features while adding or changing behavior to fit a more specific purpose. The class that represents this more specific version is the child class, also known as a subclass. It inherits what the base (or parent) class provides, then extends or overrides it for specialized needs. The base or parent class is the more general form, not the specialized one. The phrase Is-a describes the relationship between the subclass and its superclass, indicating that the subclass is a kind of the superclass, but it isn’t itself the name of a class type. So the term that directly denotes a specialized version is the child class.
