  • A super
  • B this
  • C extent
  • D extends
Correct Answer: Option D

Explanation

In Java (and many other object-oriented languages), the extends keyword is used to inherit a class. This keyword allows a subclass to inherit properties and methods from a superclass, promoting code reuse and establishing a relationship between the two classes.

Explanation:

  • A) super: This keyword is used to refer to the superclass's methods and constructors, but it does not create inheritance.
  • B) this: This keyword is used within a class to refer to the current instance, but it is unrelated to inheritance.
  • C) extent: This is not a keyword in Java.
  • D) extends: This is the correct answer, as it establishes a parent-child relationship by allowing a subclass to inherit from a superclass.
