Well, it's easy to eliminate answers A and C, because a water molecule is H2O, and if you mix an oxygen molecule, there is a more than likely chance that it'll become H2O2, which is Hydrogen Peroxide.Now, let's do the science. I'm already assuming you know this, but water is a "polar" molecule, meaning that there is an uneven distribution of electron density. Now, an oxygen molecule is nonpolar, so the answer would be letter "D." Hope this helped
