Either of the two events (notification or wait time expiration) will make the thread become a candidate for running again.

If Thread A is notified first, can it get CPU turn before the expiration of 2 sec?
Post your comments here:
Option A. Either of the two events (notification or wait time expiration) will make the thread become a candidate for running again.
Option B is incorrect because a waiting thread will not return to runnable when the lock is released, unless a notification occurs.
Option C is incorrect because the thread will become a candidate immediately after notification, not two seconds afterwards.
Option D is also incorrect because a thread will not come out of a waiting pool just because a lock has been released.
