The correct answer is option - A) five to 10 minutes.

Explanation:

Warming up is the essential part of an exercise or any physical activity or exertion by mildly stretching, jumping gently or practicing to warm up the body.  The more intense the workout is the more time one should invest in the warm-up.

Cooling the body is exactly the opposite of warm of which is achieved by relaxing the body and let the blood and body cool down after the physical exertion. Ideal time is in between five to 10 minutes for the warm-up and cool down however it depends on the type of the exercise one performing and how intense it is.

Thus, the correct answer is option A) five to ten minutes.
