D. `0.`

Answer

To determine the respiratory quotient (R.Q.) for organic acids, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Concept of R.Q.**:
- The respiratory quotient (R.Q.) is defined as the ratio of carbon dioxide (CO2) produced to the amount of oxygen (O2) consumed during respiration.
- Mathematically, it is expressed as:
\[ R.Q. = \frac{\text{CO}_2 \text{ produced}}{\text{O}_2 \text{ consumed}} \]

2. **Identify the R.Q. Values for Different Substrates**:
- For carbohydrates, the R.Q. is equal to 1. This means that the amount of CO2 produced is equal to the amount of O2 consumed.
- For proteins, the R.Q. is less than 1, indicating that more O2 is consumed than CO2 produced.
- For organic acids, the R.Q. is more than 1. This indicates that organic acids produce more CO2 than the O2 consumed during their respiration.

3. **Conclusion**:
- Since organic acids have more oxygen atoms in their structure compared to carbohydrates and proteins, they release more CO2 relative to the amount of O2 consumed.
- Therefore, the R.Q. for organic acids is more than 1.

4. **Final Answer**:
- The correct answer is that the R.Q. for organic acids is **more than 1**.
