The correct answer identifies the five K values used by EIGRP (Enhanced Interior Gateway Routing Protocol) to determine the best path for routing traffic. These K values are essential metrics that EIGRP uses to calculate its composite metric for routes.

In this context, the accurate K values are:

1. Bandwidth: This reflects the maximum speed of the link, influencing how quickly data can be transmitted.

2. Delay: This measures the time it takes for a packet to traverse the link, impacting the response times experienced in the network.

3. Load: This indicates the current traffic load on the link, helping to assess utilization.

4. Reliability: This assesses the stability and error rates of the link, which can affect overall performance.

5. MTU (Maximum Transmission Unit): Although it assists in determining packet sizes and fragmentation considerations, it isn't traditionally considered one of the K values affecting routing decisions directly.

This set of K values works together to create a formula EIGRP uses to compute the best routing paths, thus ensuring reliability and performance in route selection.
