Which of the following is not correct for virtual function in C++ ?

(A)

Must be declared in public section of class.

(B)

Virtual function can be static.

(C)

Virtual function should be accessed using pointers.

(D)

Virtual function is defined in base class.

Answer: (B)

Explanation:

(B) Virtual functions cannot be declared as static. Static member functions in C++ do not participate in dynamic binding (polymorphism), which is a fundamental feature of virtual functions. Static functions are resolved at compile time based on the type of the pointer or reference, whereas virtual functions are resolved at runtime based on the actual type of the object they’re invoked on.

So, the correct choice is (B) Virtual function can be static.
