Solution
The correct option is B Both Assertion and Reason are correct but Reason is not the correct explanation for Assertion
In the rest position, the clapper is held away from the ball a short distance, so that when it attracts by attraction force due to magnet then it should have some momentum to hit the gong. It will happen when the spring connected to the clapper should be able t give a reaction with a magnetic force so that the clapper moves toward the bell or gong.
