what causes water molecules to have a bent shape according to VSEPR theory?
a) interaction between the fixed orbitals of the unshared pairs of oxygen
b) repulsive forces between unshared pairs of electrons
c) the unusual location of the free electrons
d) ionic attraction and repulsion

The answer is (b).
There are four pairs of electrons around oxygen in a water molecule. These four electron pairs get as far apart as possible (VSEPR theory). This means that the electron pairs assume a tetrahedral electron pair geometry. The two bonding pairs of electrons will be roughly 105 degrees apart. This constitutes a "bent" molecular geometry.
