Explanation
Traffic regulation in QoS specifically refers to mechanisms that control the rate of traffic flows - policing and shaping are the two standard regulation tools. Policing (C) measures traffic against a configured rate and drops or re-marks packets that exceed it - it is a hard enforcement mechanism with no buffering. Shaping (B) also measures traffic against a rate, but instead of dropping excess packets it buffers/delays them to smooth the traffic to the configured rate. Both are regulation mechanisms because they directly control how much traffic is allowed through. Classification (A) is a marking/identification function, not regulation. Queuing (D) is a scheduling mechanism that determines the order of transmission, not a rate-control/regulation mechanism.
