C. Eosinophils
D. Monocytes

Answer

To answer the question "Which WBCs resist infections and are also associated with allergic reactions?", we can follow these steps:

### Step-by-Step Solution:

1. **Understanding White Blood Cells (WBCs)**:
- White blood cells are crucial components of the immune system. They help the body fight infections and diseases.

2. **Identifying Types of WBCs**:
- There are several types of WBCs, including lymphocytes, neutrophils, eosinophils, and monocytes. Each type has specific functions.

3. **Analyzing Each Option**:
- **Lymphocytes**:
- These are involved in the immune response, particularly in recognizing and responding to pathogens. However, they are not primarily associated with allergic reactions.
- **Neutrophils**:
- These are phagocytic cells that engulf pathogens. They play a significant role in fighting infections but are not directly involved in allergic reactions.
- **Eosinophils**:
- These WBCs are known to fight against parasitic infections and are also involved in allergic reactions. They release substances that can combat allergens and are crucial in the body's response to allergies.
- **Monocytes**:
- These cells are also phagocytic and help in engulfing pathogens. However, they do not play a significant role in allergic reactions.

4. **Conclusion**:
- Based on the analysis, the correct answer is **Eosinophils**. They resist infections and are associated with allergic reactions.

### Final Answer:
Eosinophils are the WBCs that resist infections and are also associated with allergic reactions.
