please select the best answer from the choices provided.
a
b
c
d

Explanation:

In resistance exercise, muscles work against a force (like weights, which is what option A describes). They also repeatedly contract (as in lifting and lowering weights, matching option B) and work in concerted movement (multiple muscles coordinate, matching option C). So all these aspects are true, making D the correct choice.
