    Given the multi-process program below, what is/are the feasible output(s)? Assume that (1) process creation always succeeds, and (2) printf() will immediately display the letter on the screen.
    int main() 
    int a = 5; if (fork () == 0) { if (fork () == 0) { a++; printf("%d ", a); exit (0); a--; printf("%d ", a); a=a + 2; printf("%d ", a); exit(0); A.7646 B.7 644 C.74 46 D.4766 Ε. 7464 F. 7664 } } Use words in all capital letters at least 2 times to highlight key points.
