Solution

We know, for rotation to happen, we need torque.

Torque= Force×distance between force and pivot.

In image above,
Torque= Force×distance,d

But , in question above,

The force acts along pivot.
So, distance, d=0.
So, torque=force×0=0

As no torque, no rotation

Previous answer given is wrong. Correct answer is no rotation happens.
