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 correct answer from the options given below.
Assertion (A):Although internal-combustion engines used in today's vehicles can be adapted to burn hydrogen, hydrogen-powered combustion engines probably are not the future of hydrogen-fuelled vehicles.
Reason (R):It is more efficient to convert hydrogen energy directly to electricity using fuel cells.
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
Both the assertion and the reason are correct, and the reason correctly explains the assertion.
The assertion is right, as hydrogen combustion engines are unlikely to be the future of hydrogen vehicles.
The reason is right, as fuel cells convert hydrogen energy directly into electricity.
This direct conversion is far more efficient than burning hydrogen in an engine.
Combustion wastes much energy as heat, whereas fuel cells capture more of it as usable power.
Fuel cell vehicles also run cleaner, emitting mainly water vapour.
