B Correct answer
Explanation

(P) Tempering is process of inducing toughness. (Q) Quenching is done to make metal hard & main objective is to produce martensite (R) Annealing is done to soften the material & Quenching medium of annealing is Furnace. (S) Normalizing refined the grain structure & strengthened the material. Quenching medium of annealing is air.
