Q. Suppose the size of an integer is 4 bytes, what is the output of the following code?

#include<iostream> 

using namespace std; 
  
class A { 
    int arr[10];      
}; 
  
class B: public A { }; 
  
class C: public A { }; 
  
class D: public B, public C {}; 
  
int main(void) 
{  
  cout << sizeof(D); 
  return 0; 
}

• (A) 4
• (B) 40
• (C) 80
• (D) 160
