   A retail company runs a microservices-based checkout system on Google Kubernetes Engine (GKE). Customers report that some orders fail with a 'payment declined' error, but the payment provider logs show no declined transactions. The developer needs to find which service is incorrectly handling the payment response. The application already emits structured JSON logs with a trace ID, but the logs are not currently correlated across services. What should the developer do first to identify the faulty service?

   • AEnable Error Reporting and wait for it to automatically group the payment errors by service name.
   • BUse Cloud Logging to filter logs by the trace ID of a failed order and examine the log entries from all services in the request path.
   • CDeploy a new version of the payment service with additional logging to capture the raw response from the provider.
   • DCreate a Cloud Monitoring alert on the 'payment declined' error count to detect when the issue occurs.
