A. A class can be declared inside another class

Detailed Explanation

Answer: (A) A class can be declared inside another class

C++ allows one class to be declared inside another class. Such a class is called a nested class.

For example:

class Outer {

public:

  class Inner {

  public:

    void show() { }

  };

};

Here, Inner is nested inside Outer.
