(c) Xeno or Hetero grafting
(d) Iso or syn grafting

Options

A. Auto grafting
B. Allo or Homo grafting
C. Xeno or Hetero grafting
D. Iso or syn grafting

Answer

To solve the question "Vascular grafting during CABG is an example of:", we will analyze each option provided and determine the correct answer based on the definition of the terms involved.

### Step-by-Step Solution:

1. **Understanding CABG**:
- CABG stands for Coronary Artery Bypass Grafting. This surgical procedure is performed to bypass blocked coronary arteries to improve blood flow to the heart.

2. **Identifying the Type of Grafting**:
- In CABG, a graft (which can be a vein or artery) is taken from one part of the patient's own body (like the leg or chest) and is used to create a new pathway for blood flow around the blocked artery.

3. **Analyzing the Options**:
- **(a) Auto grafting**: This refers to grafting tissue from one part of the body to another part of the same individual. Since the graft in CABG is taken from the same person, this option is correct.
- **(b) Allo or Homo grafting**: This involves grafting tissue from one individual to another of the same species but not genetically identical. This is incorrect for CABG as the tissue is not taken from another individual.
- **(c) Xeno or Hetero grafting**: This involves grafting tissue from a different species. This is also incorrect as CABG does not involve grafts from other species.
- **(d) Iso or Syn grafting**: This refers to grafting between genetically identical individuals, such as identical twins. This is not applicable in CABG since the graft is taken from the same individual.

4. **Conclusion**:
- Given the definitions and the context of CABG, the correct answer is **(a) Auto grafting**.

### Final Answer:
**(a) Auto grafting**
