Which of the following is correct set of micronutrient for plants?

Options

A. Mg, Si , Fe, Cu, Ca
B. Cu, Fe, Zn, B, Mn
C. Mg, Fe, Zn, B, Mn
D. Mo,Zn, Cl, Mg, Ca

Answer

To determine the correct set of micronutrients for plants, we need to understand the distinction between macronutrients and micronutrients.

### Step-by-Step Solution:

1. **Understand Macronutrients vs. Micronutrients**:
- Macronutrients are required by plants in larger amounts and include elements like nitrogen, phosphorus, potassium, calcium, magnesium, and sulfur.
- Micronutrients are required in smaller amounts and include elements such as iron, manganese, boron, molybdenum, copper, zinc, chlorine, and cobalt.

2. **Analyze the Options**:
- **Option 1**: Magnesium, Silicon, Iron, Copper, Calcium
- Magnesium and Calcium are macronutrients, so this option is incorrect.
- **Option 2**: Copper, Iron, Zinc, Boron, Manganese
- All these elements (Copper, Iron, Zinc, Boron, Manganese) are classified as micronutrients. This option is correct.
- **Option 3**: Magnesium, Iron, Zinc, Boron, Manganese
- Magnesium is a macronutrient, making this option incorrect.
- **Option 4**: Molybdenum, Zinc, Chlorine, Manganese, Calcium
- Calcium is a macronutrient, so this option is also incorrect.

3. **Conclusion**:
- The only option that contains only micronutrients is **Option 2: Copper, Iron, Zinc, Boron, Manganese**. Therefore, this is the correct set of micronutrients for plants.

### Final Answer:
The correct set of micronutrients for plants is **Copper, Iron, Zinc, Boron, Manganese** (Option 2).
