cis-form of complexes of type M(A A)2 B C (example [ Pt ( en )2 ClBr ]2+ are optically active. On the other hand transforms are optically inactive due to symmetry. (Unsymmetrical, optically active) and trans- (meso) -form (optically inactive)

Q. Which can exist both as diastereoisomer and enantiomer?

$[P (e n)_{3}]^{4 +}$

$[Pt (e n)_{2} ClB r]^{2 +}$

$[R u (N H_{3})_{4} C l_{2}]^{0}$

$[PtC l_{2} B r_{2}]^{0}$

cis-form of complexes of type $M (AA)_{2} BC$ (example $[Pt (e n)_{2} ClB r]^{2 +}$ are optically active.
On the other hand transforms are optically inactive due to symmetry. (Unsymmetrical, optically active) and trans- (meso) -form (optically inactive)
