Answer 2

The correct option is (B). A class may be declared as a friend.

• The friend keyword allows the user to create a class as a friend of one class.
• Thus the main class will automatically get access to the class defined using the friend keyword.
• Thus the friend keyword builds the link between two classes.
• The use of the friend keyword inside a class is to declare another class as its friend.
• Option(B) is correct.
