You use the performance timer to monitor and optimize Dynamics 365 performance. You need to view information about how many users are currently using…

The Services Session Provider performance counter provides information about active sessions on the server, which includes the total number of users currently using the application. This server-side counter aggregates session data across the Application Object Server (AOS) instance, making it the correct tool for monitoring the overall active user count as required by the scenario.

B. Web Client Session: This counter displays information specific to the current user's session in the web client, such as the number of forms they have open, not the total number of users on the system.

C. Forms: This counter provides performance metrics related to individual forms, such as the number of open forms, controls, and data sources for the current user, not system-wide user counts.

D. GC: This counter stands for Garbage Collection and provides data about .NET memory management, such as memory allocations and collections. It is unrelated to user session monitoring.
