Solution

The correct option is D compound is in cis-form
When the reactant $[C o C l_{2} (N H_{3})_{4}]^{+}$ is in cis form, the product $[C o C l_{3} (N H_{3})_{3}]$ will have have cis (or fac or facial) isomer and trans (or mer or meridional ) isomer.
When the reactant $[C o C l_{2} (N H_{3})_{4}]^{+}$ is in trans form, the product $[C o C l_{3} (N H_{3})_{3}]$ will have have only trans (or mer or meridional ) isomer.
Since two isomers of the product are obtained, the reactant is in cis form.
