Which of the following is an AFV type involving hydrogen?

Explanation:
The concept being tested is how hydrogen is used in AFV powertrains. Hydrogen/Electric Fuel Cell vehicles are the type that clearly involve hydrogen: hydrogen stored on the vehicle feeds a fuel cell, which converts it into electricity to power an electric motor. This is the hydrogen-based propulsion shown in this option. The other options rely on fuels that are not hydrogen: a gasoline internal combustion engine runs on gasoline, a diesel-only engine runs on diesel, and a coal-fueled system uses coal. None of these use hydrogen as their energy source in the way a hydrogen fuel cell vehicle does.
