Given below are two statements: one is labelled as Assertion A and the other is labelled as Reason R.
Assertion A: Leakage in a household gas cylinder can be detected
Reason R: LPG has a strong smell
In the light of the above statements, choose the most appropriate answer from the options given below:
Answer & explanation
Correct answer: option 3
The correct answer is Option (3) → A is correct but R is not correct
Assertion A: Leakage in a household gas cylinder can be detected — True. A leak is noticed at once by the strong, unpleasant smell of a substance added to the gas.
Reason R: LPG has a strong smell — False. LPG is a mixture of mainly butane and propane, and these gases are odourless. The smell of cooking gas comes from a small amount of a strong-smelling sulphur compound, ethyl mercaptan, which is added on purpose so that a leak can be noticed.
Since R is false, the question of whether it explains A does not arise.
