Answer

Brief Explanations:

Light can travel through a vacuum, so we can see the bell move as light from it reaches our eyes. Sound, however, requires a medium (like air) to travel. Since there is a vacuum inside the jar, sound waves cannot propagate, so we won't hear the bell ring.

Answer:

A. We'll see the bell move, but we won't hear it ring.
