Suggested Answer: C 🗳️
You can use extensions to configure diagnostics on your VMs to collect additional metric data.
The basic host metrics are available, but to see more granular and VM-specific metrics, you need to install the Azure diagnostics extension on the VM. The Azure diagnostics extension allows additional monitoring and diagnostics data to be retrieved from the VM.

A is more valid than C: The Linux Diagnostic Extension should be used, which downloads the Diagnostic Extension (LAD) agent on the Linux server. Reference: https://docs.microsoft.com/en-us/azure/virtual-machines/extensions/diagnostics-linux

You can use Linux Diagnostic Extension to monitor metrics and logs: https://docs.microsoft.com/en-us/azure/virtual-machines/extensions/diagnostics-linux However you can also use Performance diagnostics to collect logs and metrics (CPU, disk space, or memory) and it suports Linux as well: https://docs.microsoft.com/en-us/azure/virtual-machines/troubleshooting/performance-diagnostics So for me options A and C, both are correct.
