This question was posed to me in examination.

My doubt stems from Public Member Functions topic in section Member Functions & its Types of Object Oriented Programming

Answer 1

Right answer is (d) Public member functions can be called using object of class

The explanation: The public member functions can be called using object of the class. The members can’t be declared outside the class as those would become non-member functions of the class. The functions have security as those can be accessed using the class object only.
