B) The sound would travel half as fast, so it would take half as much time to return
C) the sound would travel twice as fast, so it would take half as much time to return
D) The sound would travel the same speed, so it would take the same amount to time to return

Answer:

D) The sound would travel the same speed, so it would take the same amount to time to return

Explanation:

The speed of sound in water is constant, decreasing the frequency will only serve to increase the wavelenght of the sound wave, it doesn't affect the speed of the Sound wave.

Speed of sound = Freq. X wavelenght
