We consider the above program for the question at the right side: The above program takes two input arguments and assigns them to x and y$,$ respectively. We consider one instance: x is initialized as $110$ and y is initialized as $220.$ We also assume that the actual pids of the parent and child are $5671$ and $5672,$ respectively. Identify the values at Lines B$,$ C$,$ D$,$ E$,$ and F by running the program:

B: pid$2=$

C: x $=$

y $=$

D: pid$1=$

E: pid$2=$

F: x $=$

y $=$
