Solution

The correct options are
B ${[C r C l_{2} {(e n)}_{2}]}_{2}^{+}$
C $[C o {(e n)}_{3}] [C o F_{6}]$
The compounds ${[P t {(b n)}_{2}]}_{2}^{2 +} a n d [Z n {(g l y)}_{2}]$ contain elements of symmetry.
Hence, they do not show optical isomerism.
The compounds ${[C r C l_{2} {(e n)}_{2}]}_{2}^{+} a n d [C o {(e n)}_{3}] [C o F_{6}]$ contain no element of symmetry.
Hence, they are optically active.
