Hint We should know that sound waves are mechanical waves that results from the back and forth of the vibration of the particles of the medium through which the sound wave is moving. The motion of the particles is parallel or in some cases anti parallel to the direction of the energy transport.

Complete step by step answer:
The speed of the sound waves given as per the question is $350m/s$.
The distance of the tree from the bat is 525 meters.
The time that is taken by the sound wave to reach the tree can be denoted as the formula given
$\dfrac{{{\text{distance}}}}{{{\text{speed}}}} = \dfrac{{525}}{{350}} = 1.5\sec$

Therefore, the correct answer is Option C.

Note: The waves are of two types. The two types are defined as transverse waves and longitudinal waves. If we want to classify the sound waves then we have to make them into longitudinal waves. It should be known that SONAR is used in the process of navigation, forecasting, weather, and for the tracking of aircraft, ships, submarines, and missiles. There are also SONAR devices that work by bouncing sound waves off objects so as to determine the location of the objects.
