Options

A. Atherosclerosis
B. Thrombosis
C. Stenosis
D. Rhinitis

Answer

**Step-by-Step Solution:**

1. **Understanding the Question**: The question asks for the term that describes the hardening of arteries due to the deposition of cholesterol on the arterial walls.

2. **Identifying Key Terms**: The key terms in the question are "hardening of arteries," "deposition of cholesterol," and "arterial wall."

3. **Exploring the Options**: The options provided are:
- Atherosclerosis
- Thrombosis
- Stenosis
- Rhinitis

4. **Defining Each Option**:
- **Atherosclerosis**: This condition involves the buildup of cholesterol, fats, and other substances on the arterial walls, leading to hardening and narrowing of the arteries, which can restrict blood flow.
- **Thrombosis**: This refers to the formation of a blood clot within a blood vessel, which can block blood flow but is not specifically related to cholesterol deposition.
- **Stenosis**: This condition involves the narrowing of spaces within the spine or heart valves, not specifically related to cholesterol.
- **Rhinitis**: This is an inflammation of the nasal mucous membrane, leading to symptoms like a runny nose, and is unrelated to arterial health.

5. **Selecting the Correct Answer**: Based on the definitions, the correct term for the hardening of arteries due to cholesterol deposition is **atherosclerosis**.

6. **Conclusion**: Therefore, the answer to the question is **atherosclerosis**.
