In the normalising process, the material is heated above critical point temperature and allowed to cool in air. The answer is D only.

Answer. D.
Normalizing is carried in still air, rate of cooling is more, it form fine pearlite with small uniform grain. So, it results in higher strength, hardness and low in ductility.

Reduced ductility means it is comparatively. Compared to annealing, ductility is less.

Ultimate tensile strength increases should be the right option.
