The closest answer to being correct is A., "Compartes la paella?"
It might be the difference between "proper" Spanish and what I know, but even that seems like it's wrong. If anything, I would ask "Compartirás la paella?"
But A. is your answer
The answer should be the last option.
The answer would be the "Breastroke" is the one you used the most meaning that when you swim you use your arms and legs.
