The answer is (B) because there are no switches in the ire that are being connected to bulb Y. Hence, bulb Y can glow but bulb X can't because S1 is not closed.

Bulb Y will still continue to glow if both the switches are open because bulb Y is directly connected to the battery and both of its terminals are connected to the battery. The answer to the given question is option b.
