The answer is (a)

Below the stone.


Actually the jerk is an impulse which quickly breaks the lower thread and the jerk is not able to transfer to the upper thread.

BUT NOTE that :-

See if the lower thread is pulled slowly then the upper thread will break first because the force which we apply on the lower thread adds up to the weight of the stone and thus breaks the upper thread first.
