Consider the following three threads executing concurrently in the same process. Semaphore s has been initialized to $1,$ while semaphore t has been initialized to $0.$

Thread $1$Thread $2$Thread $3$P$($&s$)$;P$($&t$)$;P$($&s$)$;n $*=3$;P$($&s$)$;n $+=2$;V$($&s$)$;n $*=$ n;V$($&t$)$;V$($&s$)$;V$($&s$)$;

Which of the following$$are the possible values of global variable n after all three threads have terminated? The value of n is initialized to $0.$
