Correct option is (a) True

Easy explanation: The fatigue phenomenon is generally considered as a mechanism which occurs in metallic materials. The study of the fatigue phenomenon is very necessary for considering several technical conditions which affects the fatigue life and fatigue crack growth in the material, such as the material surface quality, residual stress etc.
