The correct option is (a) True

To explain I would say: Environmental conditions can greatly affect the fatigue condition of materials which may be more severe than the sharp stress concentrations conditions. In general, corrosion and temperature are the two main environmental factors which greatly influence the fatigue behaviour of material structures.
