C. For precipitate exchange reaction
D. For no reaction

Answer

To solve the question regarding the reaction of calcium oxalate (CaC₂O₄) with acetic acid (CH₃COOH) resulting in "no reaction," we will analyze the components involved and the nature of the reaction.

### Step-by-Step Solution:

1. **Identify the Reactants:**
- The reactants in this reaction are calcium oxalate (CaC₂O₄) and acetic acid (CH₃COOH).

2. **Understand the Nature of Calcium Oxalate:**
- Calcium oxalate is a salt that is generally insoluble in water and does not readily react with weak acids. It is important to note that it requires a strong acid for any significant reaction to occur.

3. **Examine the Properties of Acetic Acid:**
- Acetic acid is a weak acid. It does not have the strength to effectively react with calcium oxalate to produce any products.

4. **Determine the Reaction Type:**
- Since calcium oxalate does not react with acetic acid, we classify this as a "no reaction" scenario. There is no change in the state of the reactants, and no products are formed.

5. **Conclude the Reaction:**
- Therefore, the overall conclusion is that when calcium oxalate is mixed with acetic acid, there is no observable reaction, and the answer to the question is "no reaction."

### Final Answer:
The correct option for the reaction of CaC₂O₄ with CH₃COOH is "no reaction."
