Given the following MPI program $($assuming everything is correct$),$ and that the mpirun command calls for $4$ processes, select the correct print statement for the process at rank $1.$ READ THE CODE CAREFULLY!!!

$==========$CODE BEGINS$============$

#include

#include

int main$($int argc, char$**$ argv$)\{$

int my$\_$rank;

$/*$ Initialize the MPI environment $*/$

MPI$\_$Init$($&argc, &argv$)$;

$/*$ Get the rank of the process $*/$

MPI$\_$Comm$\_$rank$($MPI$\_$COMM$\_$WORLD, &my$\_$rank$)$;

if $($my$\_$rank $\%2==1)\{$

printf $("$Process $\%$d is even

$",$ my$\_$rank$)$;

$\}$ else $\{$

printf $("$Process $\%$d is odd

$",$ my$\_$rank$)$;

$\}$

MPI$\_$Finalize$()$;

$\}$
