Please help. 10 points

A. Water

Explanation:

Van Helmont concluded that most of the mass the plant gained had come from water, because that was the only thing that he had added to the pot. Van Helmont's experiment accounts for the "hydrate," or water, portion of the carbohydrate produced by photosynthesis.
