← Q5 Q7 →

What is the primary objective of utilizing E100 fuel in flexible-fuel internal combustion engines?

A To completely replace State List subjects in cooperative governance
B To reduce fossil fuel imports and lower carbon emissions through high-blend bioethanol usage
C To maintain foreign currency denominated fixed deposits for non-residents
D To restrict international commercial shipping through maritime chokepoints

Correct answer: (b) To reduce fossil fuel imports and lower carbon emissions through high-blend bioethanol usage

Explanation

Option B is correct as E100 (pure hydrous ethanol) and the Ethanol Blended Petrol (EBP) programme aim to substitute crude oil imports and reduce environmental emissions. Options A, C, and D refer to cooperatives, banking deposits, and maritime security respectively, which are entirely outside the scope of automotive biofuels.
