During the process of photosynthesis the raw material used are

Options

A. Glucose
B. Chlorophyll
C. Starch
D. `CO_(2) and H_(2)O`

Answer

**Step-by-Step Solution:**

1. **Understanding Photosynthesis**: Photosynthesis is the process by which green plants and other photosynthetic organisms convert light energy into chemical energy. This process primarily occurs in the chloroplasts of plant cells.

2. **Identifying the Raw Materials**: The raw materials required for photosynthesis are carbon dioxide (CO2) and water (H2O). These are essential for the process to occur.

3. **The Role of Light and Chlorophyll**: Light energy, absorbed by chlorophyll (the green pigment in plants), is crucial for driving the photosynthesis reaction. Chlorophyll captures sunlight, which is then used to convert the raw materials into glucose and oxygen.

4. **The Overall Reaction**: The overall chemical equation for photosynthesis can be represented as:
\[ 6 \text{CO}_2 + 12 \text{H}_2\text{O} \xrightarrow{\text{light, chlorophyll}} \text{C}_6\text{H}_{12}\text{O}_6 + 6 \text{O}_2 + 6 \text{H}_2\text{O} \]
In this equation, carbon dioxide and water are the reactants, while glucose, oxygen, and water are the products.

5. **Evaluating the Options**: Given the options:
- Glucose: Incorrect, as it is a product of photosynthesis.
- Chlorophyll: Incorrect, as it is a pigment that aids in the process but is not a raw material.
- Starch: Incorrect, as it is a storage form of glucose, not a raw material.
- Carbon dioxide and water: Correct, as these are the raw materials used in photosynthesis.

6. **Conclusion**: Therefore, the correct answer is carbon dioxide and water, which are the raw materials used in the process of photosynthesis.
