In the process of photosynthesis, the gas released by green plants is ?

Options

A. Carbon dioxide
B. Nitrogen
C. Oxygen
D. None of the above

Explanation

**Step-by-Step Solution:**

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

2. **Key Ingredients for Photosynthesis**: The main components required for photosynthesis include:
- Sunlight (solar energy)
- Chlorophyll (the green pigment in plants)
- Carbon dioxide (from the atmosphere)
- Water (absorbed by the roots)

3. **Photosynthesis Equation**: The general equation for photosynthesis can be represented as:
\[ \text{6 CO}_2 + \text{6 H}_2\text{O} + \text{light energy} \rightarrow \text{C}_6\text{H}_{12}\text{O}_6 + \text{6 O}_2 \]
This means that six molecules of carbon dioxide and six molecules of water, in the presence of light energy, produce one molecule of glucose and six molecules of oxygen.

4. **Identifying the Gas Released**: During the process of photosynthesis, oxygen is produced as a byproduct. This oxygen is released into the atmosphere.

5. **Conclusion**: Therefore, the gas released by green plants during photosynthesis is oxygen.

**Final Answer**: The gas released by green plants in the process of photosynthesis is **oxygen**.
