For example, playing the piano in a recital can cause stress, but it is a very positive experience when you do well because everyone applauds and you are proud yourself. You may have felt nervous while you waited to perform, but you probably knew it was going to be a good experience. 
So the answer is C,Stress is always unhealthy and should be avoided.
