Explanation
B is correct because policing does not use buffering - it enforces a rate limit by dropping or re-marking packets that exceed the configured threshold. Since excess packets are simply discarded, policing can actually reduce bandwidth utilization rather than improve it.
A is wrong because the description in the statement - using buffering to smooth out and absorb bursts - describes traffic shaping, not policing. Shaping queues excess packets and releases them at a controlled rate, which is why shaping (not policing) improves utilization.
Memory tip: Think "Police = Punish (drop), Shape = Smooth (buffer)" - police officers issue penalties on the spot; they don't hold offenders in a waiting room.
