The complexes along with their geometrical isomers are given below:

(a) \left [ \text { Pt} \left(\mathrm{NH}_{3}\right)_{2} \mathrm{Cl}_{2} \right ] : Square planar \text{Ma}_{2}\text{b}_{2}

(b) \text{Ni}(\text{CO})_{4} : tetrahedral complex.

Does not show Geometrical isomerism.

(c) \left[\mathrm{Ru}\left(\mathrm{H}_{2} \mathrm{O}\right)_{3} \mathrm{Cl}_{3}\right] : Octahedral \text {Ma}_{3}\text{b}_{3}

(d) \left[\mathrm{Co} \mathrm{Cl}_{2}\left(\mathrm{NH}_{3}\right) _{4}\right]^{+} : Octahedral \text{Ma}_{4}\text{b}_{2}

Hence, the correct answer is option (3)
