The correct answer is C. combustion of hydrogen

In flame of pure hydrogen burning in air, the hydrogen (H2) reacts with oxygen (O2) to form water \(H_2O\) with the release of energy. 

Hydrocarbon combustion refers to the chemical reaction where a hydrocarbon reacts with oxygen to create carbon dioxide, water, and heat.

The electrolysis of brine yields chlorine, hydrogen and sodium hydroxide.
