Solution
The correct option is A Hydrogen
Hydrogen fuel is a zero-emission fuel when burned with oxygen. In a flame of pure hydrogen gas burning in air, hydrogen (H2) reacts with oxygen (O2) to form water (H2O) and releases energy.
2H2(g)+O2(g)→2H2O(g)
It is often used in internal engines, to power vehicles and electric devices. It is also used in the propulsion of spacecraft and might potentially be mass-produced and commercialized for passenger vehicles and aircraft. However, since hydrogen is so light, it rises in the atmosphere and is therefore rarely found in its pure form, i.e., H2.
