Answer:
d. Exercise comes with an inherent risk linked to intensity and frequency.
Explanation:
Actively engaging in exercise reduces the risk of a cardiac event rather than cause one so the option A is wrong. It is also very true that the risk associated with exercise is low as compared to the ones when not exercising. The human body is meant to produce heat, whether it is being exercised or not. However, the intensity and frequency of exercise does not increase the risk associated with exercising.
