A cylinderical block of density d stays fully immersed in a beaker filled with two immiscible liquids of different densities `d_1` and `d_2` The block is in equilibrium with half of it in liquid 1 and the other half in liquid 2 as shown in the Fig. If the block is given a displacement downwards released, then neglecting friction study the following statements.

A

it executes simple harmonic motion.

B

its motion is periodic but not simple harmonic.

C

the frequency of oscillation is independent of the size of the cylinder.

D

the displacement of the centre of the cylinder is symmetric about its equilibrium position.
