Question $12$

Consider the following multi$-$threaded $C$ pseudocode:bool sent $=$ false;if $($src$->$value $>=$ amount$)\{$ lock$($&dst$->$mutex$)$; unlock$($&dst$->$mutex$)$;$\}$return sent;

$\}$Which of the following calls can lead to a deadlock?

Thread A: send$\_$money$(0$x$1234,05678,50$; Thread B: send$\_$money$(0$x$5678,0$x$9876,10)$

Thread A: send$\_$money$(0$x$5678,0$x$1234,50)$; Thread B: send$\_$money$(0$x$9876,0$x$5678,10)$
