|I think option A:- fine grain => hardness increases => ductility decrease.|

|Me also with answer A as fine grain means grater grain boundaries and less dislocation movement and great ductility.|

|Compared to grain size formed in cooling in the annealing process, grain size is less in normalisating because of faster rate cooling.
So, fine grain has low ductility.
