According to werner, the arrangement of 6 groups around the metal centre within the co-ordination sphere can lead to three possible geometries (For Q. 1 and Q. 2) : planar hexagon, trigonal prism and octahedral. For a particular geometry, if the groups (i.e. ligands) are arranged in different ways then the possibility of geometrical isomerism will arise.
A complex `[PtCl_(2)(NH_(3))_(4)]^(2+)` in WERNER 'S universe has a total 3 stereo-isomers possible. If Werner was present, then, according to him, what can be the probable shape of the complex ?

Options

A. planar hexagon
B. trigonal prison
C. octahedron
D. both (a) and (b)
