Which set of inputs is required for photosynthesis in plants?

Explanation:
Photosynthesis needs light energy, water, and carbon dioxide to build sugars. Light powers the reactions inside the chloroplasts. Water provides the electrons and protons used in those reactions, and carbon dioxide supplies the carbon skeleton that becomes glucose. Oxygen is released as a byproduct, not as an input. You can think of the overall process as 6 CO2 plus 6 H2O, using light energy, yielding glucose and O2.
