@Parash.
It's asking about simple pendulum not a compound pendulum.

It depends on the Distance between the centre of suspension and centre of percussion.
So, the Answer is False.
So, the Answer is False.

A physical pendulum is the generalised case of the simple pendulum. It consists of any rigid body that oscillates about a pivot point.
For small amplitudes, the period of a physical pendulum only depends on the moment of inertia of the body around the pivot point and the distance from the pivot to the body's center of mass.
The period is still independent of the total mass of the rigid body. However, it is not independent of the mass distribution of the rigid body. A change in shape, size, or mass distribution will change the moment of inertia.
