Among the leucocytes , the largest quantity is of :

Options

A. Basophils
B. Neutrophils
C. Eosinophils
D. None of these

Answer

To determine which type of leukocyte (white blood cell) is present in the largest quantity, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Types of Leukocytes**:
- Leukocytes are divided into different types, each with a specific role in the immune system. The main types include Basophils, Neutrophils, Eosinophils, and Monocytes.

2. **Identify the Percentages of Each Type**:
- **Basophils**: 0.5% to 1%
- **Neutrophils**: 40% to 60%
- **Eosinophils**: 1% to 4%
- **Monocytes**: 2% to 8%

3. **Compare the Percentages**:
- From the percentages provided, we can see that:
- Basophils have the lowest percentage (0.5% to 1%).
- Eosinophils are slightly higher (1% to 4%).
- Monocytes have a percentage range of 2% to 8%.
- Neutrophils have the highest percentage (40% to 60%).

4. **Conclusion**:
- Since Neutrophils have the highest percentage among the leukocytes, we conclude that Neutrophils are the most abundant type of leukocyte in the body.

### Final Answer:
The largest quantity of leukocytes is Neutrophils.
