Of what liquified petroleum gas (LPG) is mainly made up of ?

Options

A. Methane, Butane, Propane
B. Methane, Ethane, Propane
C. Methane, Ethane
D. Methane

Explanation

### Step-by-Step Solution:

1. **Understanding Liquefied Petroleum Gas (LPG)**:
- LPG stands for Liquefied Petroleum Gas, which is a type of fuel that is used for heating, cooking, and as fuel for vehicles.

2. **Main Components of LPG**:
- LPG is primarily composed of two hydrocarbons: **butane (C4H10)** and **propane (C3H8)**. These are the main constituents that make up LPG.

3. **Presence of Other Gases**:
- In addition to butane and propane, LPG may also contain a small amount of **methane (CH4)**. However, the primary components remain butane and propane.

4. **Safety Considerations**:
- Both butane and propane are odorless gases. To ensure safety and detect leaks, a chemical called **methyl mercaptan (CH3SH)** is added to LPG. This compound has a strong odor, which helps in identifying gas leaks.

5. **Conclusion**:
- Therefore, the main components of liquefied petroleum gas (LPG) are butane and propane, with a small amount of methane present.

### Final Answer:
Liquefied Petroleum Gas (LPG) is mainly made up of **butane and propane**.
