Options

A. `[NiBr_(2)(Pet_(3))_(2)]" and "[Cu(NH_(3))_(5)Cl]^(2+)` have same geometrical but different magnetic properties.
B. `[Co(NH_(3))_(3)Cl]Cl_(2)" and "K_(4)[Cr(CN)_(6)].3H_(2)O` both are inner orbital complexes but the former is diamagnetic and later one is paramagnetic with two unpaired electrons.
C. `[Co(NH_(3))_(2)Cl_(2)(en)]^(+)` can have total five stereo isomeric forms.
D. Complex `[Pt(NH_(3))_(4)][PtCl_(6)]` can show coordination isomerism.
