Kriti performed the following two experiments.
I. She held a hack-saw blade with a pair of tongs and then kept the tip of the free end on the flame. She observed that the blade became red hot.

Identify the types of changes occurring in both the experiments.

A I - Physical change, II - Chemical change
B I - Chemical change, II - Physical change
C Both I and II - Physical changes
D Both I and II - Chemical changes
