$1$ point

Consider that you have two transactions, T$1,$ with timestamp $1$ and T$2,$ with timestamp $2.$

Consider the following start of a schedule $($using basic locks$)$: $l_1(x)$;$r_1(x)$;$u_1(x)$;$l_2(x)$;dots

What transaction, if any, will restart as part of operation $4$ after having run that start when you are using Wound$/$Wait for deadlock prevention?

T$1$ will restart

T$2$ will restart

Both T$1$ and T$2$ will restart

Neither T$1$ nor T$2$ will restart

The schedule can not be run at all, since there is a deadlock
