Solution

The correct option is A $[P t {({N H}_{3})}_{6}] {C l}_{4}$
Molar conductivity $\propto$ no. of ions present after dissociation
${[P t {({N H}_{3})}_{6}] C l}_{4} \to {[P t {({N H}_{3})}_{6}]}^{4 -} + 4 {C l}^{(-)}     $
5 ions
Hence, it has a maximum molar conductivity.
