The QoS mechanism that prioritises delay-sensitive traffic such as VoIP is c. Priority Queuing (PQ).

Here's a step-by-step explanation:

1. Quality of Service (QoS) mechanisms are used in networks to prioritize different types of traffic. This is important when the network is congested and not all packets can be delivered immediately.

2. VoIP (Voice over IP) is a type of traffic that is very sensitive to delay. If VoIP packets are delayed, the quality of the voice call can be significantly reduced.

3. Priority Queuing (PQ) is a QoS mechanism that can be used to prioritize VoIP traffic. With PQ, packets are put into different priority queues. Packets in the highest priority queue are always sent first.

4. Therefore, by putting VoIP traffic in the highest priority queue, PQ can ensure that VoIP traffic is always sent before other types of traffic, reducing the chance of delay.

5. The other options, Class-Based Weighted Fair Queuing (CBWFQ), Weighted Fair Queuing (WFQ), and Random Early Detection (RED) are also QoS mechanisms, but they do not prioritize traffic in the same way as PQ. They use different methods to manage network congestion and distribute bandwidth among different types of traffic.
