it is the third one: \[{\text{2}}{{\text{H}}_{\text{2}}}{\text{ + }}{{\text{O}}_{\text{2}}} \to {\text{2}}{{\text{H}}_{\text{2}}}{\text{O}}\] since we have four atoms of hydrogen at both sides, and we have 2 atoms of oxygen at both sides

It is the first option, since hydrogen has only one valence electron, whereas oxygen has 6 valence electrons
