Choose odd one out w.r.t. gaseous cycle.

Options

A. Carbon
B. Hydrogen
C. Nitrogen
D. Phosphorus

Answer

### Step-by-Step Solution:

1. **Understanding Gaseous Cycles**:
Gaseous cycles refer to the natural processes that involve the exchange of gases in the atmosphere. Examples include the nitrogen cycle, carbon cycle, and hydrogen cycle.

2. **Identifying the Options**:
We need to evaluate the given options to determine which one does not belong to the category of gaseous cycles. The options are:
- Carbon Cycle
- Hydrogen Cycle
- Nitrogen Cycle
- Phosphorus Cycle

3. **Analyzing Each Option**:
- **Carbon Cycle**: This is a gaseous cycle as it involves the exchange of carbon dioxide and other carbon compounds in the atmosphere.
- **Hydrogen Cycle**: This is also a gaseous cycle as it involves the movement of hydrogen in gaseous forms.
- **Nitrogen Cycle**: This is a gaseous cycle as it includes the exchange of nitrogen gases in the atmosphere.
- **Phosphorus Cycle**: This is not a gaseous cycle. The phosphorus cycle is classified as a sedimentary cycle because phosphorus does not exist in a gaseous state in the atmosphere; it primarily exists in solid and liquid forms.

4. **Conclusion**:
Based on the analysis, the odd one out with respect to gaseous cycles is the **Phosphorus Cycle**.

### Final Answer:
The odd one out with respect to gaseous cycles is the **Phosphorus Cycle**.
