You are presented with the quiz "What should be done to replace body fluids?" 

But you don't know the answer, so you turn to your teacher to ask for hints. He says that "thirst is used to make an animal realize that it needs to replenish its bodily water by the body" and "to replenish body fluids, drink adequate amounts of water or a non-caffeinated beverage". 

So, what's the best answer to the question?
