Consider the code below and choose the correct option:

main(){
    int child = fork();
    int c = 5;
    if(child == 0)
        c += 5;
    else{
        child = fork();
        c += 10;
        if(child)
            c += 5;
    }
}

(A) Total 3 processes are there with value of variable c as 5, 10, and 15.
(B) Total 3 processes are there with value of variable c as 10, 15, and 20.
(C) Total 3 processes are there with value of variable c as 10, 15, and 15.
(D) Total 4 processes are there with value of variable c as 10, 15, 15, and 20.
