Solution

The correct option is B
A lighted splint

When a metal reacts with dilute hydrochloric acid, hydrogen gas is evolved which does not support burning but itself burns with a pale blue flame. Hence it not cause the glowing splint to catch fire. But with a lighted splint, the hydrogen gas itself will catch fire with a pop sound.
