Expert Answer:

correct answer is

a) at a slower rate

Bromination of alkanes occurs by a mechanism similar to chlorination of alkanes, but is slower and more selective because a bromine atom is a less reactive hydrogen abstraction agent than a chlorine atom, as reflected by the higher bond energy of H-Cl than H-Br. Bond energy of H-Cl bond is 432 kJ/mol and that of H-Br bond is 366 kJ/mol.
