An ideal spring is wrapped around a cylinder that is free to rotate with negligible friction about a stationary horizontal axis. The free end of the string is attached to a massive object. When the object is released from rest at a heigh h above the floor gravity pulls it downward causing the string to unwind and the cylinder to turn. The time it takes for the object to reach the floor:

A. Is independent of the moment of inertia of the cylinder.

B. Get longer if the cylinder is replace with one having larger moment of inertia.

C. Gets shorter if the cylinder is replaced with one having larger moment of inertia.
