C. `R-underset(OH)underset(|)C=NH`
D. `R-C-=overset(o+)NH`

Answer

To determine the intermediate product of hydrolysis of cyanide, we can analyze the process step by step.

### Step-by-Step Solution:

1. **Understanding Cyanide Hydrolysis**:
- Cyanides (R-C≡N) can undergo hydrolysis in both acidic and basic conditions to form different products. The hydrolysis process involves the addition of water (H₂O) to the cyanide.

2. **Hydrolysis in Basic Medium**:
- In a basic medium, hydroxide ions (OH⁻) attack the carbon atom of the cyanide (R-C≡N).
- This results in the formation of an intermediate product, which is an amide (R-C(=O)-NH₂).

3. **Formation of Amide**:
- The reaction proceeds with the formation of an amide as the intermediate product. The reaction can be summarized as:
- R-C≡N + OH⁻ → R-C(=O)-NH₂ (amide)

4. **Further Hydrolysis**:
- The amide can further react with hydroxide ions to eventually form a carboxylic acid (R-COOH). However, the question specifically asks for the intermediate product, which is the amide.

5. **Hydrolysis in Acidic Medium**:
- In acidic conditions, the nitrogen of the cyanide is protonated (R-C≡NH⁺), and then water attacks to form an amide (R-C(=O)-NH₂) as well.
- The steps are similar to those in the basic medium, leading to the same intermediate product.

6. **Conclusion**:
- In both acidic and basic hydrolysis of cyanide, the intermediate product formed is an amide (R-C(=O)-NH₂). Therefore, the correct answer is that the intermediate product of hydrolysis of cyanide is an amide.

### Final Answer:
The intermediate product of hydrolysis of cyanide is **R-C(=O)-NH₂ (amide)**.
