Well #1# is the answer I would choose.

Explanation:

Because oxygen is quite electronegative it is conceived to polarize electron density towards itself. And this is often use to explain the polarity of water, and the capacity of water to solvate and separate positive and negative ions.

And so we would represent this as...#""^(""^+delta)H-stackrel(delta^-)O-H^(delta^+)#

....and since the hydrogens lie on the outside boundary of the water molecule, we select #1#. But it is a bit of a whack question.
