Match List-I (Fuel Type) with List-II (Example) and choose the correct answer from the options given below.
Wind power is a non fuel, biodiesel is an alternative fuel, compressed natural gas is a nontraditional fossil fuel, and the hydrogen fuel cell is an emerging fuel.
Wind power drives turbines directly without any fuel being consumed, so it is a non fuel source.
Biodiesel substitutes for conventional diesel from renewable feedstock, so it is an alternative fuel.
Compressed natural gas is a fossil fuel used in a less conventional gaseous form, so it is a nontraditional fossil fuel.
The hydrogen fuel cell is a newer clean technology, so it is an emerging fuel.
Together these span the range from natural flows to fossil sources and new energy carriers.
