Answer» RIGHT option is (a) Using access declaration for private MEMBERS of base class The best I can explain: If using access declaration for private members of base class was allowed in programming, it would have destroyed whole CONCEPT of encapsulation. As if it was possible, any class which gets inherited PRIVATELY, would have been able to inherit the private members of base class, and hence could access each and EVERY member of base class. |
