Which statement accurately describes photosynthesis?

Photosynthesis uses light energy captured by chlorophyll to drive a series of reactions that convert carbon dioxide and water into organic sugars and oxygen. Light powers the splitting of water and the fixation of CO2 into carbohydrates, with oxygen released as a byproduct. An important detail is that the oxygen comes from water, not CO2, while CO2 is what becomes the sugars. This makes the statement accurate because it correctly describes the involvement of water, CO2, chlorophyll, and light in producing carbohydrates and O2. The other ideas misstate the process: sugars aren’t produced directly from sunlight by chlorophyll alone without CO2; CO2 is indeed involved; and oxygen isn’t the sole product.
