The correct answer would be A, 5 to 10 minutes of jogging/walking or 5 to 10 minutes of static stretching exercise.
Explanation:
Cool Down is a period right after the intense exercise. This is the period where a person let his body cool down after a hard workout session. Cool Down period is very important. This time period allows the body muscles to relax. This period must include 5 to 10 mins of light walking or 5 to 10 minutes of static stretching exercises. Stretching exercises are more recommended because by doing this, the muscles of the body get relaxed and you won't feel pain or cramps in different parts of your body where you worked out the most at that day.
