**(c)**

Let be the length of the cylinder in water it is in the vertical position and be the cross-sectional area of the cylinder. As cylinder is floating so

Weight of cylinder = upward thrust or

When the cylinder is tilled through an angle , length of cylinder in water

Weight of water displaced

Restoring force
