D. Ca

Answer

To solve the question "Find the odd out with respect to micronutrients," we need to analyze each option provided and determine which one does not belong to the category of micronutrients.

### Step-by-Step Solution:

1. **Understand Micronutrients**: Micronutrients are essential nutrients that organisms need in small quantities. They include minerals and vitamins that play crucial roles in various biological functions.

2. **Evaluate Each Option**:
- **Option 1: Manganese**: Manganese is classified as a micronutrient. It is essential for various enzymatic processes in plants and animals.
- **Option 2: Boron**: Boron is also a micronutrient. It is important for plant growth and development, particularly in cell wall formation and reproductive processes.
- **Option 3: Copper**: Copper is another micronutrient. It is vital for the functioning of several enzymes and plays a role in iron metabolism.
- **Option 4: Calcium**: Calcium is primarily known as a macronutrient. While it is essential for various physiological functions, it is required in larger amounts compared to the other options listed.

3. **Identify the Odd One Out**: After evaluating all the options, we find that:
- Manganese, Boron, and Copper are all classified as micronutrients, while Calcium is generally categorized as a macronutrient. Therefore, Calcium is the odd one out.

4. **Conclusion**: The correct answer is **Option 4: Calcium**.
