In total WBCs, lymphocytes are `:-`

Options

A. `60-65%`
B. `2-3%`
C. `6-8%`
D. `20-25%`

Answer

To determine the percentage of lymphocytes in total white blood cells (WBCs), we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Types of WBCs**:
- White blood cells (WBCs) are crucial for the immune response and are classified into five main types: neutrophils, eosinophils, basophils, monocytes, and lymphocytes.

2. **Identify the Categories**:
- WBCs can be divided into two categories:
- **Granulocytes**: neutrophils, eosinophils, and basophils.
- **Agranulocytes**: monocytes and lymphocytes.

3. **Know the Normal Ranges**:
- The normal percentage ranges for each type of WBC in a healthy adult are approximately:
- Neutrophils: 40-60%
- Eosinophils: 1-4%
- Basophils: 0.5-1%
- Monocytes: 2-8%
- Lymphocytes: 20-40%

4. **Focus on Lymphocytes**:
- According to the information provided, lymphocytes constitute about 20-40% of the total WBC count.

5. **Select the Correct Answer**:
- The question provides several options for the percentage of lymphocytes in total WBCs:
- 60-65%
- 2-3%
- 6-8%
- 20-25%
- Based on the normal range for lymphocytes, the closest and most accurate option is **20-25%**.

### Final Answer:
Lymphocytes make up approximately **20-40%** of the total WBCs, and the best answer from the options provided is **20-25%**.
