Answer: A
Explanation:
The three reactants used in photosynthesis are water (H2O) carbon dioxide (CO2), and light (sunlight energy). These reactants are used to produce glucose/food for plants and oxygen that is later released.
This is the chemical formula for photosynthesis. Instead of just saying "Energy," however, it should specify solar energy, or light energy. Photosynthesis is the process of capturing solar energy and converting it to chemical energy.
