उत्तर
If A is true, but R is false.
Explanation:
Assertion (A) is true because LPG (Liquefied Petroleum Gas) and CNG (Compressed Natural Gas) burn cleanly without producing smoke, ash, or significant harmful emissions, making them excellent eco-friendly household and vehicular fuels. However, reason (R) is false because the primary constituents of these two gases are completely different. LPG is mainly propane and butane, whereas CNG consists almost entirely of methane, so they do not share the same chemical composition.
