I will also go with option C. But option D is right, when we will make explicit calls to both functions present in Base and Derived.
So, if we do not make any explicit call to the base class function, then it will call function of Derived class, as we are creating the object of the same.

No its wrong answer. Derived class object will call always derived class function irrespective of base class. This is called as function overriding.

It will raised an ambiguity error cause compiler will confused when we create the object of derived class.

I also agree with option B because both class contain same prototype. Prefrence gives to base class.

Ya ! answer is B only.
Base class method will call all the time even we are calling derived class method so to reduce this problem we need to use Virtual function concept.

We can declare both base & derived class objects and as per that we can directly call the functions of that class.

Only base class constructor is called.

I am confused about objects but yes when we use base class pointer base class function is called irrespective of the address to which it is pointing to.

The correct answer is B.
If you call function with derived class object it calls base class function.
To prevent this you have to use virtual function concept.

The answer given is right as it totally depends on calling class object.
