Stereoisomerism arises on account of different positions and arrangement of lignads in space around the metal ion . These are classified into two types : (i) Geometrical isomerism is exhibited by octahedral and square planar complexes . (ii) Optical isomerism is shown when mirror images are non superimposable. The compound(s) that exhibi(s) geometrical isomerism is(are) :A. `[Pt(en)Cl_(2)]`B. `[Co(OH_(2))_(4)Cl_(2)]Cl`C. `[Pt(en)_(2)Cl_(2)]Cl_(2)`D. `[Pt(NH_(3))_(2).Cl_(2)]`
