Why does a water molecule have a bent shape? O A. The protons in the nucleus of the hydrogen atoms repel the protons in the nucleus of the oxygen atom. B. The oxygen atom has lone pairs of electrons. has two covalent bonds . D. The hydrogen atoms repel each other.

Because of the higher electronegativity of the oxygen atom, the bonds are polar covalent (polar bonds). The molecule adopts a bent structure because of the two lone pairs of electrons on the oxygen atom.
