Which of the following can be considered as the members that can be inherited…

In C++-style object-oriented programming (the convention this class of exam question follows), inheritance and access control are two independent things: an access specifier (public, protected, or private) decides whether a base-class member's name can be referenced directly from a piece of code, while inheritance decides whether that member becomes part of the derived class's object at all. A member can therefore be inherited -- physically present in every derived-class object -- without the derived class's own code being permitted to reference it directly by name.

Applying this rule to each access specifier shows a clear pattern:

Public and protected members are both inherited and directly nameable inside the derived class, so neither matches a pattern of 'inherited but not accessible'. Private members are the only row where 'inherited' is paired with 'not directly nameable'.

This matches the standard C++ access-control rule that this style of exam question follows: derived-class code can call an inherited public or protected member directly by name, but can reach an inherited private member only indirectly, through a public or protected method that the base class itself provides -- it can never write the private member's name directly inside the derived class.

So the members that are inherited into a derived class but not directly accessible within it are the Private members.
