$CH_{3}-F > CH_{3}-Cl > CH_{3}-Br > CH_{3}-I$

(B) The bond enthalpy of the $C-X$ bond depends on the bond length. As we move down the group in the periodic table,the atomic size of the halogen $(X)$ increases. This leads to an increase in the $C-X$ bond length. As the bond length increases,the bond strength (and thus bond enthalpy) decreases. Therefore,the correct order of bond enthalpy is $CH_{3}-F > CH_{3}-Cl > CH_{3}-Br > CH_{3}-I$.
