c. take the "no pain, no gain" approach.

B- avoid sedentary behavior such as sitting too much.

A

I believe the answer is A due to b saying you should only work out 3-4 times a month which isn’t true, C saying to take the no pain, no gain approach which has been proven to unbenefical and D saying to choose only vigorous activitices, workouts don’t need to always be vigorous.
