The answer is C. stress is always healthy and should be avoided. Eustress is known to be stress that the person reacts to in a positive way. It is a moderate or normal psychological stress interpreted as being beneficial for the experiencer. An example of Eustress, would be a challenging work assignment that is perceived to be neither too difficult nor too easy. Hope this helped :))
