### Breakdown of the Problem
We need to identify which term describes the ballooning of a weakened portion of an arterial wall from the given options.

### Relevant Concepts
- An **aneurysm** is a dilation or ballooning in the wall of an artery due to weakness.
- **Thromboangiitis obliterans** (Buerger's disease) is a condition affecting blood vessels.
- **Varicosities** refer to enlarged veins, often in the legs, that do not directly relate to arteries.
- **Emboli** refers to particles that travel through the bloodstream and can cause blockages.

### Analysis and Detail
1. **Aneurysm**: It specifically refers to the abnormal enlargement of an artery, which matches the description of ballooning.
2. **Thromboangiitis obliterans**: More related to vascular inflammation rather than structural weaknesses.
3. **Varicosities**: Related to veins rather than arteries, making it irrelevant here.
4. **Emboli**: This term refers to debris in the blood flow, missing the aspect of arterial wall structure.

### Verify and Summarize
The definition of an aneurysm directly fits the description provided in the question, while the other terms do not relate to the structural changes in arterial walls.

### Final Answer
The correct answer is **a. aneurysm**.
