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)
C(A) is correct but (R) is not correct
D(A) is not correct but (R) is correct
Correct answer: (A) Both (A) and (R) are correct and (R) is the correct explanation of (A) — Both the assertion and the reason are correct and the reason correctly explains the assertion, so that is the answer.
Explanation
★Both the assertion and the reason are correct and the reason correctly explains the assertion, so that is the answer.
★Solid waste buried in a landfill can still be a source of energy, so the assertion is correct.
★Organic waste decomposes in the landfill and produces methane, a natural gas.
★This gas can be captured through landfill gas recovery systems.
★The captured gas is then burned to generate heat and electricity.
★So the production of usable natural gas directly explains how buried waste provides energy.
