C Correct answer
Explanation

Hydrogen fuel is completely pollution free; the only by-product in its combustion is water. The conversion of hydrogen into liquid is a costly process. Because hydrogen is a gas, it cannot be compressed into a liquid form without intensive cost and energy input. Hydrogen is difficult to store and distribute.
