Correct answer
A. A - Q B - S C - P D - R
Step-by-step solution
[ Pt ( NH ₃)₂ Cl ₂] is a square planar complex of the type MA₂B₂ . It exhibits cis-trans isomerism. This matches Q. [ Ni ( NH ₃)₂ Cl ₂] is a tetrahedral complex of the type MA₂B₂ since Ni ²⁺ is a 3d^8 ion and forms sp^3 hybridized complexes with weak field ligands. Tetrahedral complexes do not exhibit geometrical isomerism, and since it lacks four different ligands, it does not show optical isomerism. Thus, it does not exhibit isomerism. This matches S. [ Co ( NH ₃)₃( NO ₂)₃] is an octahedral complex of the type MA
