Best answer
Right choice is (a) True

The explanation: In the hot working of steel material, the carbon content can be disturbed; means the carbon loss can occur from the surface of steel metal which leads to losing of its strength. This is a major drawback which can also weaken the surface layer that gives rise to fatigue crack which may further result in complete failure of the metal component.
