it is C because you always have a chance that you will cause an injury. No matter how fit you are you will expeirence fatigue at some point. and it is good to change ur exercise routine but dont completely quit it

I believe the answer is: C. sustain a regular routine of exercise for 30-60 minutes with minimal fatigue.

Our body is run through constant supply of oxygen. When we do aerobic exercise, the amount of oxygen supply needed to our body would be increased. So, when we keep pushing ourselves to the limit of our cardiovascular capability, our muscle would start to experience fatigue as a defense mechanism to reduce oxygen usage.
