- Option : B
- Explanation : Program P( ) { x = 10; y = 3; funb (y, x, x) print x; print y; } funb (x, y, z) { y = y + 4; z = x + y + z; } Since, It is call by reference then address will be pass as argument: i.e. P( ) { x = 10; y = 3; funb (&y, &x, &x) print x; print y; } funb (x, y, z) //funb (&y, &x, &x) // { y = y + 4; //at &x 14 will be assigned // z = x + y + z; // Now &x will be assigned with 3 + 14 + 14 = 31. } There is no change in y and x is updated twice when printf called it will print x = 31 and y = 3. So, option (B) is correct.
