Question

When throwing a ball, why does the triceps muscle contract?

Answer 1

Answer:

I think it might be A, it seems the most reasonable.

Explanation:

the reason why I say that is because

B, contraction is more tense and it is shortened meaning it wouldn't be able to relax so it wouldn't extend.

C, it doesn't really give you a explanation of why the tricep muscle contracts.

D, triceps are made to relax, which means it is the opposite of contraction because the tricep needs to relax in order for the bicep to contract.

Sorry if I'm wrong :/
