Solution

The correct option is D Both (b) and (c) shows geometrical isomerism
(a) [Ni(H $_{2}$ O) $_{5}$ NH $_{3}$ ] $^{2 +}$ neither shows geometrical isomerism nor shows optical isomerism.
(b) [Ni(H $_{2}$ O) $_{4}$ (NH $_{3}$ ) $_{2}$ ] $^{2 +}$ shows cis-trans isomerism and (c) [Ni(H $_{2}$ O) $_{3}$ (NH $_{3}$ ) $_{3}$ ] $^{2 +}$ shows fac-mer isomerism which is nothing but goemetrical isomers.
Thus, (b) and (c) shows geometrical isomerism.
