Correct Option: C

Photosynthesis in plants converts radiant energy from the sun into chemical energy in the form of glucose (sugar) using electrons and protons from water. Plants take in water, carbon dioxide, and sunlight and turn them into glucose and oxygen. Water (6H₂O) + Carbon Dioxide (6CO₂) + Sunlight (Radiant Energy) = Glucose (C₆H₁₂O₆) + Oxygen (6O₂).
