The correct response is:

The clock will slowly become quieter and will ultimately fade from view.

As the air is removed from the space around the clock, the sound will gradually become fainter because sound requires a medium (like air) to travel through. As the air is removed, the medium for sound waves decreases, making the sound less audible. Eventually, when there is very little air left, the clock may become less visible as well.
