What is the output of this program?

#include <iostream>
    using namespace std;
    class Example 
    {
        public:
        void FunctionA() 
        { 
            cout << "Function A" << endl;
        }
        int num;
    };
    void (Example :: *ptr1)() = &Example :: FunctionA;
    int Example :: *ptr2 = &Example :: num;
    int main() 
    {
        Example object;
        Example *ptrObject = new Example;
        (object.*ptr1)();
        (ptrObject ->* ptr1)();
        object.*ptr2 = 3;
        ptrObject ->* ptr2 = 4;
        cout << object.*ptr2 << endl
        << ptrObject ->* ptr2 << endl;
    }

1. Function A
  Function A
2. Function A
  3
  Function A
3. Function A
  3
  4
  Function A
4. 3
  4
  Function A
  Function A
5. Function A
  Function A
  3
  4

Correct Option: E

In this program, As we are passing the value twice to the method
in the class, It is printing the Function A twice and then it is printing the given value.
