Given below are two statements, one labelled as Assertion (A) and the other as Reason (R). In the light of the above statements, choose the most appropriate answer from the options given below.
Assertion (A):Even when a solid waste is buried in landfills, it can still provide energy.
Reason (R):Buried waste produces natural gas which can be captured and burned.
ABoth A and R are correct and R is the correct explanation of A ✓ Correct
BBoth A and R are correct but R is not the correct explanation of A
CA is correct but R is not correct
DA is not correct but R is correct
Correct answer: (A) Both A and R are correct and R is the correct explanation of A
Explanation
Solid waste buried in a landfill can still yield useful energy over time.
The assertion is correct because decomposition inside the landfill releases a burnable gas.
The reason is correct because buried waste generates natural gas as it breaks down.
This gas is mainly methane, produced by anaerobic microbes deep in the covered waste.
Because that captured gas is what supplies the energy, the reason explains the assertion.
Recovered landfill gas can be flared for safety or piped to generate electricity.
