The command that will help determine and isolate issues on the network side in this scenario is A. mtr.

MTR (My Traceroute) is a diagnostic tool used to measure the network connection quality between two network endpoints by identifying and reporting where in the network the connection may be experiencing issues. It combines the functionality of the ping and traceroute commands by continuously sending packets to the destination and displaying the results in a live, updating format.

The output of the MTR command shows the latency and packet loss at each hop between the local host and the destination. It provides a visual representation of the path and timing of each network hop, which can be useful in identifying the location of the bottleneck in the network.

On the other hand, dig is a command-line utility for querying DNS servers to obtain information about domain name resolution, netstat is used to display active network connections, and route is used to display and modify the routing table.

Therefore, in this scenario, MTR is the most appropriate tool for troubleshooting high latency values and determining if the issue is on the network side.
