Nucleus of granuler WBC is mainly `:-`

Options

A. Spindle shape
B. Round
C. Oval shape
D. Lobed

Answer

To answer the question regarding the shape of the nucleus of granular white blood cells (WBCs), we can break it down step by step:

### Step-by-Step Solution:

1. **Identify Granular WBCs**:
- Granular WBCs are a type of white blood cell that contain granules in their cytoplasm. The main types of granular WBCs are eosinophils, basophils, and neutrophils.

2. **Examine Eosinophils**:
- Eosinophils have a bilobed nucleus. This means that the nucleus is divided into two lobes, which are connected by a thin strand of nuclear material.

3. **Examine Basophils**:
- Basophils have an S-shaped nucleus. This nucleus does not have a distinct lobular structure like eosinophils but is instead shaped like the letter 'S'.

4. **Examine Neutrophils**:
- Neutrophils have a pentalobed nucleus. This means that their nucleus is divided into five lobes, which are connected by thin strands of nuclear material.

5. **Conclusion**:
- All three types of granular WBCs (eosinophils, basophils, and neutrophils) have lobed nuclei. Therefore, the nucleus of granular WBCs can be described as lobed.

### Final Answer:
The nucleus of granular WBCs is mainly lobed.
