The answer to this question is C) ALO2
<span>When electrons shared unequal atoms such as hydrogen
and oxygen atom, one atom will get more of the common electrons and it will be slightly
negatively charged. The other atoms who gets less electron will be slightly
positively charged. This chemical condition describes water as a polar
molecule. The oxygen atom pulls the shared electrons more strongly than do the
hydrogen atoms within each of the two polar covalent bonds.</span>
