Please explain it.

At this position the displacement is maximum.

Let's understand it as " the mean position".

So, the mean position is at the centre of the pendulum motion. Clearly, at the centre there is no motion and hence, acceleration is zero.

We know that velocity= differentation(s/t).

And acceleration = differentation(v/t).
since at mean position displacement(s)=0.
then velocity =0 and acc =0.
s=displacement.
v velocity.

Acceleration= w^2 y.
y=0.
than acceleration becomes 0.

It is for instant acceleration. A= w^2 are where r is zero.

Option A is the correct answer.

Their is no restoring force acting while it is on mean position so acceleration is zero.
