Which of the following represents the correct order of oxidising power of halogens in water?

Assertion $(A)$: The bond dissociation energy increases from $F_2$ to $Cl_2$ and then decreases to $I_2$.
Reason $(R)$: The low bond energy of fluorine is due to the repulsion between the lone pairs of electrons in two fluorine atoms.
