   A DevOps team deploys a new microservice and wants to understand its behavior in production. They instrument the code to emit structured JSON logs, collect HTTP request metrics, and add trace IDs to each request. The team's goal is to quickly answer 'why is the service slow for a specific user?' Which combination of telemetry types is most directly needed to answer this question?

   • ALogs and metrics, because logs contain the user ID and metrics show the overall service performance.
   • BOnly metrics, because they provide aggregate performance data that can be drilled down by user.
   • CMetrics and traces, because metrics show the slowdown and traces reveal the path and timing of that specific request.
   • DTraces and logs, because traces show the request path and logs contain the error messages.
