Which statement correctly explains the polarity of the water molecule?

a. the hydrogen end of the molecule has a partial negative charge and the oxygen end has a partial positive charge.

b. the oxygen end of the molecule has a partial negative charge and the hydrogen end has a partial positive charge.

c. both ends of the molecule have a partial negative charge, which attracts the other water molecule towards itself.

The oxygen end of the molecule has a partial negative charge and the hydrogen end has a partial positive charge. This is because of the electronegativities of the atoms O and H. O is more electronegative than H so electrons are more often around the O atom. Electrons are negatively charged, so this causes the partial negative charge on the O atom, similarly, the "deficiency" of electrons around the H atoms cause partial positive charges because the nuclear charge (protons) isn't balanced to the number of electrons around it.

Hope this helps :)
