B. Water absorbed by the roots.

Water is essential for plant growth and is absorbed by the roots to help facilitate the process of photosynthesis, which is needed for the production of new leaves. Starch stored in the roots may provide energy for the plant, but water is necessary for the growth and development of new leaves. Fertilizer may provide essential nutrients for the plant, but it is not the source of energy needed for leaf growth. Photosynthesis primarily occurs in the leaves, not in the roots.
