Solution:

(a) I is trans form which has centre of symmetry as well as plane of symmetry; so optically inactive.
(b) II is cis form which lacks centre of symmetry as well as plane of symmetry; so optically active.
(c) (II) and (III) lack symmetry elements; so both are optically active.
(d) IV is trans form which has centre of symmetry as well as plane of symmetry; so optically inactive.
