Solution:
Step 1: Understand Correlation ID propagation
Correlation IDs are passed along services to maintain traceability of the same request.Step 2: Identify logging behavior in downstream services
Service B should log the same Correlation ID it received to keep the trace consistent.Final Answer:
Service B logs include the same Correlation ID received from Service A -> Option CQuick Check:
Correlation ID propagation = Same ID logged [OK]
Quick Trick: Downstream services log received Correlation ID [OK]
