I need to ask this question from Base Class in section Classes of Object Oriented Programming

Answer 1

Correct answer is (a) It is parent of any of its derived class

The explanation: A class which is parent of another class, or from which other classes can be derived, is known as a base class. It is mandatory that a class must have at least one derived class to be called as a base class.
