Right choice is (b) False

The explanation is: Fatigue under corrosion is called as corrosion fatigue which is a very complex problem. It mainly refers to the combination of corrosive environment and repeated stress, which can be more detrimental than the other conditions. Repeated stress accelerates the corrosion in material which further accelerates the fatigue conditions in the material.
