Correct Answer

Explanation

The correct answer is: Polymorphism

Polymorphism is one of the four fundamental pillars of Object-Oriented Programming (OOP). The other three pillars are:

Encapsulation: Involves bundling data and methods that operate on the data into a single unit (class) and controlling access to the internal details of the object.
Inheritance: Allows a new class (subclass or derived class) to inherit attributes and methods from an existing class (superclass or base class), promoting code reuse.
Polymorphism: Enables objects of different types to be treated as objects of a common type. This can occur at compile time (compile-time polymorphism) through method overloading and operator overloading, and at runtime (run-time polymorphism) through method overriding.

So, while superclass and subclass are related to inheritance, and variable is a general term in programming, polymorphism is a specific pillar of Object-Oriented
