Solution

The correct option is C Method of measuring the depth of the sea
Echo sounding is a type of sonar used to determine the depth of water by transmitting sound waves into water.

The time interval between emission and return of a pulse is recorded, which is used to determine the depth of water along with the speed of sound in water at the time.
Hence option C is the correct answer.
