When the vibration is in a direction parallel to wave's motion that is a Longitudinal wave  (C).

But When the vibration is in a direction perpendicular to wave's motion then it is Transverse wave.

Answer: The correct option is C.

Explanation:

Longitudinal wave is a wave in which the particles of the medium vibrate parallel to the direction of the wave. For example, sound wave. Longitudinal wave needs medium to travel. It can travel in solid, liquid and gas.

Transverse wave is a wave in which the particles of the medium move perpendicular to the direction of the wave. For example, light wave. Transverse wave does not need any medium to travel.

Therefore, longitudinal wave causes the medium to vibrate only in a direction parallel to the wave's motion.
