Which of the following nutrition is provided to soil from fertilizers ?
(i) Potassium (ii) Iron
(iii) Nitrogen (iv) Phosphorus

Options

A. (i), (ii), (iii)
B. (ii), (iii), (iv)
C. (i), (iii), (iv)
D. (i), (ii), (iv)

Explanation

To determine which nutrients are provided to soil from fertilizers, we can analyze the options given:

1. **Understanding Fertilizers**: Fertilizers are substances added to soil to provide essential nutrients that promote plant growth. They typically contain macronutrients and micronutrients.

2. **Identifying Macronutrients**: The primary macronutrients that fertilizers provide are Nitrogen (N), Phosphorus (P), and Potassium (K). These are often referred to as NPK.

3. **Reviewing the Options**:
- (i) Potassium: This is a macronutrient provided by fertilizers.
- (ii) Iron: This is a micronutrient and is generally not included in fertilizers.
- (iii) Nitrogen: This is a macronutrient provided by fertilizers.
- (iv) Phosphorus: This is also a macronutrient provided by fertilizers.

4. **Conclusion**: Based on the analysis, the nutrients provided to soil from fertilizers are:
- Nitrogen (iii)
- Phosphorus (iv)
- Potassium (i)

5. **Final Answer**: The correct options that indicate nutrition provided to soil from fertilizers are (i) Potassium, (iii) Nitrogen, and (iv) Phosphorus.
