• D. Nitrogen gas and minerals

Answer: (C)

Verified step by step guidance

1. Understand that photosynthesis is the process by which plants convert light energy into chemical energy stored in glucose.
2. Recall the general photosynthesis equation: \$6 \text{CO}_2 + 6 \text{H}_2\text{O} + \text{light energy} \rightarrow \text{C}_6\text{H}_{12}\text{O}_6 + 6 \text{O}_2$.
3. Identify the raw materials on the left side of the equation, which are carbon dioxide (\(\text{CO}_2\)) and water (\(\text{H}_2\text{O}\)).
4. Recognize that oxygen (\(\text{O}_2\)) and glucose (\(\text{C}_6\text{H}_{12}\text{O}_6\)) are products, not raw materials, of photosynthesis.
5. Conclude that the correct raw materials required for photosynthesis are carbon dioxide and water.
