Solution

The correct option is A Both Statement 1 and Statement 2 are correct and Statement 2 is the correct explanation of Statement 1.
We require energy to break water molecules into $H^{+} a n d O H^{-}$ ions, but the amount of energy release during the formation of $H_{2} a n d O_{2}$ is much more than that of water molecule, so the energy require for bond brakage is compensated by the energy of bond formation.
