The most accurate response is:
The appearance of the clock will not change, but its sound will become fainter.
As air is removed from around the alarm clock, the sound waves produced by the clock will have less medium (air) to travel through, causing the sound to become fainter. However, the appearance of the clock itself will remain unchanged since it is still visible regardless of the air pressure around it.
