K-12 ! What is the role of motivation in physical activity?

Motivation helps you to achieve your goals.

Motivation is supported by a variety of activity.

Motivation is what keeps you going in the moment where you might want to give up.

All of the above

I think the answer is 'Motivation is what keeps you going in the moment where you might want to give up'

Explanation:

Now, I'll just set the answers into letters just to make this explanation quick and simple. First answer is A, Second is B, Third is C, and ofc the last is D.

A is just saying what motivation can do, yes. But it's just stating what it can only do as that role, same thing applies for B. That's why C is the answer. It is practically A and somewhat some part of B.
