(D) Optical activity in coordination complexes is observed when the complex lacks a plane of symmetry and its mirror image is non-superimposable on the original structure.Among the given options,the complex $[M(B)_2(en)_2]$ (where $en$ is ethylenediamine) exists in cis and trans forms.The cis-isomer of $[M(B)_2(en)_2]$ lacks a plane of symmetry and is chiral,thus exhibiting optical activity.The other complexes listed possess planes of symmetry in their most stable configurations,making them optically inactive.

Which of the following complexes exhibits optical activity?
