Option is D. $foo$ is printing the lowest digit. But the $printf$ inside it is after the recursive call. This forces the output to be in reverse order $2, 0, 4, 8$ The final value $sum$ printed will be $0$ as $C$ uses pass by value and hence the modified value inside $foo$ won't be visible inside $main$.
