   Your development team is building a new microservice in Go that will run on Google Kubernetes Engine (GKE). They want to instrument the service with custom metrics and traces using a vendor-neutral API, and they want the telemetry to be exported to Google Cloud Monitoring and Cloud Trace. The team also wants to avoid vendor lock-in for future multi-cloud deployment. What should you recommend?

   • AUse the Cloud Monitoring client library directly in the Go service to create custom metrics and traces.
   • BUse the OpenTelemetry SDK in the Go service and configure the OTLP exporter to send data to the Google Cloud exporter.
   • CInstrument the service with Prometheus client libraries and scrape metrics using Google Cloud Managed Service for Prometheus.
   • DDeploy the Ops Agent as a sidecar container in the GKE pod to collect metrics and traces from the application.
