It will compile successfully but will not execute as main is the very first function to be called and it is called every time by say a master program running somewhere behind and from there the further references are given by us to do whatever required acc to need.
So it will only compile not execute.

It Can be compiled successfully because as the protected (access specifier) helps peacock class only (child class) to get accessthrough the methods and variables of birds class (parent class).
But here there will be no output because there are no methods or variables in both the class.

This particular code "snippet" does not have any errors. THUS option D is correct. Of Course to run you will need a main function.
The : is not scope resolution operators. That is how classes are inherited in C++.

It will compile successfully. We can have a empty class and can inherit protected from any class. Nothing will be displayed on console as we are not writing anything to console.

The code will compile properly. Since the existence of class is only by object of that particular class and there are know syntax error in the code.

It'll compile as protected access specified provides inheritance or data member functions accessibility only to the next immediate derived class.

We can read the above statement as "peacock is a a bird". Class peacock is a class which inherits from class bird, in a protected manner.

The above program compile successfully. Because in this program a class is defined in another class with protected specifier.

There is no error in this program. It does not matter whether the body is defined or not. It will compile successfully.
