Correct Answer

C

Explanation

The phenomenon that makes sound persist when its source has been removed is known as "reverberation" or "echo." Reverberation occurs when sound waves reflect off surfaces in an environment and continue to bounce around, creating a persistence of sound even after the initial source of the sound has stopped producing sound waves. Echo specifically refers to a distinct repetition or reflection of sound, often heard as a distinct repetition of the original sound with a delay. Both reverberation and echo are common in various natural and man-made environments.
