Select the option that contains micronutrients only

Options

A. Mn, Mo, Zn
B. C, H, N
C. N, P, O
D. Mn, K, S

Answer

To solve the question of selecting the option that contains micronutrients only, we can follow these steps:

### Step-by-Step Solution:

1. **Understand Micronutrients**:
- Micronutrients are essential nutrients that plants require in small amounts for their growth and development.

2. **List of Micronutrients**:
- The essential micronutrients for plants include:
- Boron (B)
- Zinc (Zn)
- Manganese (Mn)
- Iron (Fe)
- Copper (Cu)
- Molybdenum (Mo)
- Chlorine (Cl)

3. **Evaluate Each Option**:
- Look at each option provided and check if all elements listed are part of the micronutrient list.
- **Option 1**: Contains Manganese, Molybdenum, and Zinc. All of these are on the micronutrient list, so this option is correct.
- **Option 2**: Contains Carbon, Hydrogen, and Nitrogen. None of these are micronutrients, so this option is incorrect.
- **Option 3**: Contains Nitrogen, Phosphorus, and Oxygen. None of these are micronutrients, so this option is incorrect.
- **Option 4**: Contains Manganese, Potassium, and Sulphur. While Manganese is a micronutrient, Potassium and Sulphur are not, so this option is incorrect.

4. **Conclusion**:
- After evaluating all the options, the only option that contains only micronutrients is **Option 1**.

### Final Answer:
- The correct answer is **Option 1**.
