a. a molecule moves through its normal position to the opposite side of its normal position.
b. a molecule moves in the same direction as a wave.
c. the vibration results in a molecule moving vertically.
d. the vibration of the point in the medium ends.

The scenario that would cause a sound to stop being produced is when a molecule moves through its normal position to the opposite side of its normal position. The answer is letter A. This is also known as destructive interference.
