Options

A.
B.
C.
D.

Answer

To answer the question about which diagram Tarun should draw after observing white blood cells under a microscope, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Structure of White Blood Cells**:
- White blood cells (WBCs) are crucial components of the immune system. They help defend the body against infections and foreign invaders.

2. **Identify the Types of White Blood Cells**:
- WBCs can be classified into two main categories:
- **Granulocytes**: These cells contain granules in their cytoplasm. They include neutrophils, eosinophils, and basophils.
- **Agranulocytes**: These cells do not have granules. They include lymphocytes and monocytes.

3. **Examine the Nucleus of White Blood Cells**:
- The nuclei of white blood cells can vary in shape. They can be:
- **Bilobed**: Two lobes connected by a thin strand.
- **Multilobed**: More than two lobes, often seen in neutrophils.
- **Single Lobe**: A single, round nucleus, typically seen in lymphocytes.

4. **Select the Appropriate Diagram**:
- Given the characteristics of WBCs, Tarun should choose a diagram that accurately represents the various types of nuclei found in white blood cells.
- The correct diagram (Diagram B) should depict a variety of nuclear shapes, including bilobed and multilobed nuclei, which are characteristic of different types of granulocytes.

5. **Conclusion**:
- Tarun should draw Diagram B, as it best represents the diversity of white blood cells he observed, showcasing the different types of nuclei.
