    1. C - it has the most carbon atoms and so can smother the fire effectively, while the others are too reactive due to the predominantly halogen composition

    from first to last: bromination, nitration, alkylation: the benzene ring reacts differently to differing reactants, bromine is the most polar of the three, nitrogen the next and alkyls the least.
