The one that will show optical activity is ( en = ethane - 1 ,   2 - diamine)

Solution

Plane of symmetry exists.
Hence, does not show optical isomerism.

This structure has a plane of symmetry.
Hence, no optical isomerism.

No plane of symmetry it shows optical isomerism.

Plane of symmetry, so it does not show optical isomerism.
