Best answer
The correct choice is (b) Square planar

To elaborate: The CN of the metal ion is 4 because Cl^– is a unidentate ligand. The only possibility for the shape of its coordination polyhedra is square planar or tetrahedral. From crystal field splitting diagram, it is known that [PtCl4]^2- is square planar.
