In the figure, the disc `D` does not slip on the surface `S`, the pulley `P` has mass and the string does not slip on it. The string is wound around the disc.

A

The acceleration of the block B is doubled the acceleration of the centre of D.

B

The force of friction exerted by D on S acts to the left.

C

The horizontal and the vertical sections of the string have the same tension.

D

The sum of the kinetic energies of D and B is less than the loss in the potential energy of B as it moves down.
