Which one of the following is the exhaust pipe emission from Fuel Cell Electric Vehicles, powered by hydrogen?

Accepted Answer

Fuel cell electric vehicles (FCEVs) are powered by hydrogen. They are more efficient than conventional internal combustion engine vehicles and produce no harmful tailpipe emissions—they only emit water vapor and warm air. Hence option (d) is the correct answer.
