I am pretty sure that the stage in the free radical substitution of methane by chlorine which will have the lowest activation energy is B Cl • + Cl • → Cl 2. I choose this option because during termination there is no breaking of bonds within two reactive  radicals which are joined together.

Do hope it will help you!
