Your architecture calls for the centralized collection of all admin activity and VM system logs within your project.
How should you collect these logs from both VMs and services?

A. All admin and VM system logs are automatically collected by Stackdriver. B. Stackdriver automatically collects admin activity logs for most services. The Stackdriver Logging agent must be installed on each instance to collect system logs. C. Launch a custom syslogd compute instance and configure your GCP project and VMs to forward all logs to it. D. Install the Stackdriver Logging agent on a single compute instance and let it collect all audit and access logs for your environment.
