The correct answer is:
C

I is trans form which has centre of symmetry as well as plane of symmetry ; so optically inactive

II is cis form which lacks centre of symmetry as well as plane of symmetry ; so optically active

(II) and (III) lack symmetry elements ; so both are optically active.

IV is trans form which has centre of symmetry as well as plane of symmetry ; so optically inactive
