The particles will move up and down over small areas.
Option B.
Step-by-step explanation:
The type of the wave that has been discussed in the question is the transverse kind of wave. The transverse kind of wave are the waves where the particle motion is the perpendicular to the motion of the wave.
In the transverse kind of wave the which is a moving kind of a wave where the oscillations are perpendicular to the direction of the movement of the wave.
