Consider the following program:

Answer:
The solution of this question is given below in explanation section.
Explanation:
The correct answer to this question is A i.e. 112002 .
the correct code of this question is given below
#include <stdio.h>
#include <string.h>
#include <sys/types.h>
//#include "csapp.h"
void end(void)
{
printf("2");
}
int main()
{
if (fork() == 0)
atexit(end);
if (fork() == 0)
printf("0");
else
printf("1");
exit(0);
}
/* $end forkprob2 */
when you run this program, fork function print different values.
However, it is noted that when you run the program repeatedly, it will show you different values. But the most possible value that this program will show is A.
The picture is attached of the running program to get the idea of code.

Explanation:
(a)
Here, distance between hosts A and B is m meters and, propagation speed along the link is s meter/sec
Hence, propagation delay,
(b)
Here, size of the packet is L bits
And the transmission rate of the link is R bps
Hence, the transmission time of the packet,
(c)
As we know, end-to-end delay or total no delay,
(d)
The expression, time means the\at time since transmission started is equal to transmission delay.
As we know, transmission delay is the time taken by host to push out the packet.
Hence, at the last bit of the packet has been pushed out or transmitted.
(e)
If
Then, at the bit has been transmitted from host A, but to condition (1), the first bit has not reached B.
(f)
If
Then, at , the first bit has reached destination on B
Here,
It's given that
Hence,
