Answer:
I believe the answer is B.
Explanation:
I believe that you shouldn't use l<span>ow intensity (light weights) if you want to build muscle mass.
</span>These types of weights won't help you much define the muscles you want to have, as opposed to free weights, weight machines, and high intensity (heavy weights) which definitely will. So if your goal is to build muscle mass, avoid light weights.
All of the above, they all apply.
B would be the best answer from the choices shown above
