Consider the following code for signaling and signal handlers in parent and child processes, respectively.

int x, y;

void catch ctic (ant sig num)

(x = 1: y = 1:1

void catch_user (int sig_num)

{x = 2; y = 2; ]

int main

{ signal(SIGINT, catch _ctic);

signal(SIGRTMIN, catch_user);

int pid = fork ();

if (pid != 0)

[kill (pid, SIGINT);

kill (pid, SIGTMIN);

else { scan"%d", &x); // read 5

scanf(*%d", &y); // read 6 printf (*(%d,%din", x, y);

}

wait();

}

What may be the printouts for (x,y) in the program above?

A. (1,1)

B. (2.2)

C. (1.2)

D. (2,1)

E. (1.6)

F. (2.6)

G. (5.1)

H. (5.2)

I. (5.6)

Your answer should be the labels) of all the above that apply, in alphabetical order with no space (e.g., ABD).
