Answer:

C. 30 min minutes a day 5 days a week of moderate-intensity exercise or 20 minutes a day 3 days a week of vigorously intense exercise

Adults need a moderate physical aerobic activity for a minimum of 30 minutes 5 days a week or 20 minutes of vigorous-intensity aerobic activity. A combination of these two can be done to achieve this goal.

The muscle-strengthening activity, should be performed for a minimum of 2 days a week on two or more nonconsecutive days.
