Solution
The correct option is D I, II, IV PH5 does not exist because the energy difference between d- and s-orbitals of P and H, respectively is very high. pπ−dπ bond is present in SO2−4 due to overlapping of fully occupied p-orbitals of O with empty d-orbitals of S. I+3 has a bent shape due to presence of two lone pair of electrons.
