Answer: The correct option is B.
Explanation:
Reflection of the sound is a process in which the sound bounces back after striking the object without getting absorbed in it.
The reflection of the sound phenomenon is used by a bat to detect its prey.
The bat emits ultraviolet wave and then this wave is reflected back to the ears of bat. In this way, a bat enables to detect how far its prey is.
Therefore, the sound waves a bat releases hit an object and are reflected back to the bat.
