B. High quality sleep
C. Mental clarity
D. Good boy composition
B.) In order to get high quality sleep, our body needs to be active during the day, which exhausts us (In a good and healthy way), so that we can get the proper amount of rest needed.
C.) Physical health is very important, sometimes vital, to achieve mental clarity. When we exercise, we exhude hormones, so that they don't get shoved and stashed into the epicenter of all our decisions-our mind.
D.) Obviously, in order to achieve a desirable and healthy body composition, activity is required. When we sweat, run, jump, climb-whatever exercise or activity it may be- we are getting steps and steps closer to attaining that good body composition everyone seems to want.
Hope this helps :)
