D. They are polar and form hydrogen bonds.

Explanation:

Water (H₂O) is a polar molecule due to the electronegativity differential between the bonds between hydrogen (H) and oxygen (O) atoms in water. In other words, water is polar because oxygen (which is much more electronegative) does not share all electrons with hydrogen, leaving a pair of unpaired electrons.

In addition, the polarity of water molecules allows them to easily bond together, with the positive end of one (hydrogen) binding to the negative end of another (oxygen), these interactions are called hydrogen bonds.
