The correct response is:

There are two atoms of hydrogen and one atom of oxygen in a water molecule.

This is because water (H₂O) consists of two hydrogen atoms bonded to one oxygen atom, which is why the decomposition of water results in producing twice as much hydrogen gas (H₂) as oxygen gas (O₂).
