Options
\[\ce{2H2(1) + O2(1) -> 2H2O(g)}\]
\[\ce{2H2(g) + O2(1) -> 2h2O(1)}\]
\[\ce{2H2(g) + O2(g) -> 2H2O(1)}\]
\[\ce{2H2(g) + O2(g) -> 2H2O(g)}\]

Solution
\[\ce{2H2(g) + O2(g) -> 2H2O(g)}\]
Explanation:
H2 and O2 are gases at room and elevated temperatures. The reaction is carried upon strong heating. At this temperature, H2O formed is in gaseous state.
