(C) The bond length of carbon-halogen bonds increases as the size of the halogen atom increases.The order of bond lengths is: $C-F Since bond energy is inversely proportional to bond length,the bond energy decreases as the bond length increases.Therefore,the order of bond energies in descending order is: $C-F > C-Cl > C-Br > C-I$.
