D. acetylene and hydrogen

Explanation

To answer the question about the composition of domestic cooking gas, we can follow these steps:

### Step-by-Step Solution:

1. **Identify the Components of Domestic Cooking Gas**:
- Domestic cooking gas is primarily used for cooking and heating purposes. It is commonly known as Liquefied Petroleum Gas (LPG).

2. **List the Main Constituents**:
- The main constituents of domestic cooking gas are:
- Methane (CH₄)
- Propane (C₃H₈)
- Butane (C₄H₁₀)

3. **Understand the Role of Each Component**:
- **Methane**: This is the simplest alkane and is a major component of natural gas. It burns cleanly and is efficient for cooking.
- **Propane**: This is used for heating and cooking, especially in areas where natural gas is not available.
- **Butane**: This is also used in cooking and is commonly found in portable gas stoves.

4. **Conclusion**:
- Therefore, domestic cooking gas consists mostly of methane, propane, and butane.

### Final Answer:
Domestic cooking gas consists mostly of methane, propane, and butane.
