Well I do say from my studies and experience, that a warm up should be less intense than the exercise, because you don't wan't to workout to hard before getting to the main exercise, that's like having a huge appetizer then then main course meal. So my final answer would be C. Hope this helps

I believe the answer is the Exhaustion stage because it is the bodies reaction to stress. The body becomes extremely susceptible to sickness because it seems to lose to respond to any new stress. Hope I helped!
