Answer

To analyze the statements provided in the question, we will evaluate each statement step by step.

### Step 1: Evaluate Statement A
**Statement A:** Atherosclerosis is a type of Coronary Artery Diseases (CAD).

- **Explanation:** Atherosclerosis is indeed a type of coronary artery disease. It involves the buildup of fats, cholesterol, and other substances in and on the artery walls, which can restrict blood flow. This condition is a significant contributor to heart attacks and other cardiovascular issues. Therefore, Statement A is **correct**.

### Step 2: Evaluate Statement B
**Statement B:** Monocytes are the least abundant granulocytes.

- **Explanation:** Monocytes are a type of white blood cell (WBC) involved in the immune response. However, they are not classified as granulocytes; they are categorized as agranulocytes. Granulocytes include neutrophils, eosinophils, and basophils. Among the granulocytes, basophils are the least abundant. Thus, Statement B is **incorrect**.

### Conclusion
- **Final Assessment:** Statement A is correct, while Statement B is incorrect. Therefore, the correct option is that only Statement A is true.
