Answer:
A. Transverse Wave
Explanation:
A wave in which oscillations are perpendicular to the motion's direction is called as transverse wave. Here it is evident that the pattern is same like a transverse wave. Example: take a string, tie one end to something and create a wave by moving it up and down from the other end, the wave thus generated is a transverse wave.
Longitudinal wave: when oscillations occur along the same direction as that of the motion.
Surface wave: It is a combination of transverse and longitudinal waves.
