Carbon dioxide, water, and sunlight are the raw materials for photosynthesis. Photosynthesis is the process by which green plants make their own food from carbon dioxide and water in the presence of sunlight. The prepared food is glucose. To prepare one molecule of glucose, by the process of photosynthesis six molecules of carbon dioxide and six molecules of water is required. Six oxygen molecule is released as a byproduct.
Thus, the correct product are 'Carbon dioxide, water, and sunlight'.
