• D. Water.
• E. Sunlight.

Answer: (A)

Verified step by step guidance

1. Understand the process of photosynthesis: Photosynthesis is a process used by plants, algae, and some bacteria to convert light energy, usually from the sun, into chemical energy stored in glucose.
2. Identify the reactants and products: The general equation for photosynthesis can be written as: 6CO₂ + 6H₂O + light energy → C₆H₁₂O₆ + 6O₂. This shows that carbon dioxide and water are used to produce glucose and oxygen.
3. Focus on the main product: In the context of photosynthesis, the main product refers to the primary substance that is synthesized and stored as a result of the process. In this case, it is glucose (C₆H₁₂O₆).
4. Differentiate between products and by-products: While oxygen is also produced during photosynthesis, it is considered a by-product. The main purpose of photosynthesis is to produce glucose, which serves as an energy source for the plant.
5. Conclude with the correct answer: Based on the understanding of the photosynthesis process, the main product is glucose, which is the primary energy storage molecule synthesized by plants.
