Solution

The correct answer is Method overriding. This concept in Java allows us to implement runtime polymorphism. Here's why:

  1. Polymorphism in Java is a concept by which we can perform a single action in different ways. Polymorphism is derived from 2 Greek words: poly and morphs. The word "poly" means many and "morphs" means forms. So polymorphism means many forms.

  2. There are two types of polymorphism in Java: compile-time polymorphism and runtime polymorphism. We can perform polymorphism in java by method overloading and method overriding.

  3. If you overload a static method in Java, it becomes the compile-time polymorphism. If you override a method in Java, it becomes the runtime polymorphism.

  4. Therefore, the concept that allows us to implement runtime polymorphism in Java is Method overriding.
