Right answer is (c) No, because friend function can only access private members of friend class

The explanation: The friend function of class B will not be able to access private members of class A. Since B is inheriting class A privately, the members will become private in class B. But private members of class A won’t be inherited at all. Hence it won’t be accessible.
