Micronutrients in plants include

Options

A. Mn,Ni,Zn
B. Mg,Mn,Mo
C. Cu,B,O
D. Ca,S,Fe

Answer

**Step-by-Step Solution:**

1. **Understand the Classification of Nutrients:**
- Nutrients in plants are classified into two main categories: macronutrients and micronutrients.
- Macronutrients are required in larger quantities, while micronutrients are needed in smaller amounts.

2. **Identify Micronutrients:**
- Micronutrients include elements that are essential for plant growth but are required in trace amounts. Common examples include:
- Manganese
- Nickel
- Zinc
- Molybdenum
- Copper
- Boron
- Iron

3. **Review the Given Options:**
- The question provides a list of nutrients, and we need to identify which of them are classified as micronutrients.
- For example, if the options include Magnesium, Nickel, Zinc, Copper, Boron, Calcium, and Iron, we need to categorize them.

4. **Categorize Each Element:**
- **Magnesium**: Macronutrient (needed in larger amounts)
- **Nickel**: Micronutrient (needed in trace amounts)
- **Zinc**: Micronutrient (needed in trace amounts)
- **Copper**: Micronutrient (needed in trace amounts)
- **Boron**: Micronutrient (needed in trace amounts)
- **Calcium**: Macronutrient (needed in larger amounts)
- **Iron**: Micronutrient (needed in trace amounts)

5. **Select the Correct Group:**
- From the analysis, the correct group of micronutrients includes Nickel, Zinc, Copper, and Boron.
- Therefore, the correct answer to the question is the group that contains these elements.

**Final Answer:**
Micronutrients in plants include Nickel, Zinc, Copper, and Boron.
