Answer 1

The correct choice is (b) Each class can access only non-private members of its parent

Best explanation: The classes will be able to access only the non-private members of its parent class. The classes are using private inheritance, hence all the members of the parent class become private in the derived class. In turn those won’t be allowed for further inheritance or direct access outside the class.
