Answer:
The correct Option is (a) please see attachment containing complete question.
Explanation:
1) The motion is basic to and fro motion of an object.
2) Considering the motion as Simple Harmonic Motion (SHM), the graph tells us that the pendulum appears to be moving to the left and slowing down being acted upon positive acceleration.
3) Reaching the left extreme, it stops i.e. V = 0 m/s, and then starts moving to the right due to the component of gravity (g), speeding up.
