Correct Answer:
C. Propane and Butane
The correct answer is Propane and Butane. LPG (Liquefied Petroleum Gas) is primarily a mixture of propane (C₃H₈) and butane (C₄H₁₀). It is produced during natural gas processing and petroleum refining and is widely used as a fuel for cooking, heating, and vehicles. Among the options:
- Methane and Ethane: These are the main components of natural gas (CNG), not LPG.
- Helium and Neon: These are noble gases, not flammable fuels.
- Propane and Butane: Correct; these are the primary components of LPG.
- Oxygen and Nitrogen: These are the main components of air, not LPG.
Hence, the correct answer is "Propane and Butane".
