B. B
C. Fe
D. Zn

Answer

To answer the question regarding which mineral is required in larger amounts compared to other micronutrients, we can follow these steps:

### Step-by-Step Solution:

1. **Understand Micronutrients**: Micronutrients are essential elements required by plants in small quantities for their growth and development. They include minerals such as iron, manganese, zinc, copper, molybdenum, and boron.

2. **Identify the Key Micronutrients**: Among the various micronutrients, we need to identify which one is required in larger amounts.

3. **Focus on Iron**: Iron is a crucial micronutrient that is often highlighted in discussions about plant nutrition. It plays a significant role in various physiological processes.

4. **Role of Iron in Plants**:
- Iron is essential for chlorophyll synthesis, which is vital for photosynthesis.
- It activates several enzymes, including catalase, which is important for the breakdown of hydrogen peroxide.
- Iron is a key component of proteins such as ferredoxin and cytochrome, which are involved in electron transport and energy transfer in cells.

5. **Comparison with Other Micronutrients**: While all micronutrients are important, iron is typically required in larger quantities than other micronutrients like manganese, zinc, and copper.

6. **Conclusion**: Based on the information gathered, we can conclude that iron is the mineral required in larger amounts compared to other micronutrients.

### Final Answer:
Iron is the mineral required in larger amounts in comparison to other micronutrients.
