Hello!
A polar molecule is where one of the atoms in a molecule has a slight positive charge, and another has a slight negative charge, due to the unequal sharing of electrons.
Water is one of these molecules - the electrons spend more time around the oxygen atom in the center, and less around the hydrogens, so the hydrogen atoms have a slight positive charge, and the oxygen a slight negative.
Therefore, your answer is B, water has a slight negative and a slight positive charge at opposite poles.
Hope this helps!
