In which of the following both pairs have correct combination?

Options

A. `{:("Gaseous nutrient cycle", "Sulphur and Phosphorus"),("Sedimentary nutrient cycle", "Carbon and Nitrogen"):}`
B. `{:("Gaseous nutrient cycle", "Sedimentary nutrient cycle"),("Carbon and Nitrogen", "Sulphur and Phosphorus"):}`
C. `{:("Gaseous nutrient cycle", "Carbon and Sulphur"),("Sedimentary nutrient cycle", "Nitrogen and Phosphorus"):}`
D. `{:("Gaseous nutrient cycle", "Nitrogen and Sulphur"),("Sedimentary nutrient cycle", "Carbon and Phosphorus"):}`

Answer

To solve the question about which pairs have the correct combination of nutrient cycles and their corresponding elements, we can follow these steps:

### Step-by-Step Solution:

1. **Understand Nutrient Cycles**:
- There are two main types of nutrient cycles:
- **Gaseous Nutrient Cycles**: These involve the exchange of nutrients between the atmosphere and living organisms.
- **Sedimentary Nutrient Cycles**: These involve the exchange of nutrients from the Earth's crust (lithosphere) to living organisms.

2. **Identify Elements Associated with Each Cycle**:
- **Gaseous Nutrient Cycles**:
- Common examples include **Carbon** and **Nitrogen**.
- **Sedimentary Nutrient Cycles**:
- Common examples include **Sulfur** and **Phosphorus**.

3. **Match Elements with Their Correct Cycle**:
- For **Gaseous Nutrient Cycles**:
- Carbon → Gaseous Cycle
- Nitrogen → Gaseous Cycle
- For **Sedimentary Nutrient Cycles**:
- Sulfur → Sedimentary Cycle
- Phosphorus → Sedimentary Cycle

4. **Determine the Correct Combinations**:
- Based on the above identification:
- Gaseous Nutrient Cycle: Carbon and Nitrogen (Correct)
- Sedimentary Nutrient Cycle: Sulfur and Phosphorus (Correct)

5. **Conclusion**:
- Both pairs have the correct combinations. Therefore, the correct answer to the question is the second option.

### Final Answer:
The correct answer is the second option, where both pairs have the correct combination:
- Gaseous Nutrient Cycle: Carbon and Nitrogen
- Sedimentary Nutrient Cycle: Sulfur and Phosphorus
