ANSWER

For A :The molecule, which rs optically active, has chiral centre, is expected to rotaie the plane of polarised light.

For C :Two chiral centres, but plane of symmetry within moiecule ⇒ optically inactive

For D: Molecule has chiral centre is expected to rotate plane polarised light.

Hence,option A and D is correct.
