Oxygen is more electronegative than hydrogen, meaning that it likes to pull electrons towards itself more than hydrogen does. Since oxygen likes 2 electrons, it will bond to 2 hydrogen atoms, pulling 1 electron towards itself from each hydrogen. This produces a partial positive charge on the hydrogen and a partial negative charge on the oxygen.

The answer is D (in english)
