What happens if a derived class function does not override a virtual function from its base class?

A compilation error
The base class function is used
The program crashes at runtime
The derived class function becomes abstract

The correct answer is: The base class function is used

If a derived class function does not override a virtual function from its base class, the base class function is used. Virtual functions allow for polymorphism, where the same function can behave differently based on the type of object calling it. By not overriding the virtual function, the derived class is essentially inheriting and using the implementation from the base class. Hence, the correct answer is B.
