Answer: D

Explanation:

Quality of Service (QoS) packet classification can be performed using different fields in the packet headers. The Type of Service (TOS) field in the Layer 3 header is used for this purpose. It allows network devices to classify packets based on the level of service they require. This classification is crucial for managing network traffic effectively, ensuring that high-priority services receive the bandwidth and low-latency treatment they need.
