A) AACBDD

B) ABADCD

C) AADBCD

D) BAADCD

Consider the following C program that uses the POSIX API: if (p == #include #include int main() { char a = 'A', b = 'B', c = 'C', d = 'D'; pid_t p = fork(); write (STDOUT_FILENO, &a, 1); 0) { write (STDOUT_FILENO, &b, 1); } else { waitpid(p, NULL, 0); write (STDOUT_FILENO, &c, 1); } write(STDOUT_FILENO, &d, 1); } Given char x = 'A';, running write (STDOUT_FILENO, &x, 1) outputs A to stdout. Assume that calls to fork, write, and waitpid do not fail. Two possible outputs of this program are AABDCD and ABDACD. Which of the following are also possible outputs? Select all that apply
