A Correct answer
Explanation

Generally, metal salts are impregnated with some defects like metal excess defects and metal deficiency defects. NaCl and AgBr exhibit metal excess defects. FeO, FeS and NiO exhibit metal deficiency defects. Hence, the correct answer using the codes is P - 1, Q - 2, R - 2, S - 2, T - 1.
