student c: some of the water is used by the plant to make food, and some water moves through the plant and…

Brief Explanations:

The statement describes two primary biological processes involving water in plants. First, "water is used by the plant to make food" refers to photosynthesis, where water ($H_{2}O$) and carbon dioxide ($CO_{2}$) are chemically converted into glucose and oxygen using light energy. Second, "some water moves through the plant and leaves without changing" refers to transpiration. In this process, water is absorbed by the roots, travels through the xylem, and evaporates into the atmosphere through the stomata in the leaves as water vapor, remaining chemically as $H_{2}O$ throughout the cycle.

Answer:

The statement describes the processes of photosynthesis and transpiration.
