   An administrator is troubleshooting a slow transaction. The flow map shows the transaction calls a database and a message queue. The database call takes 200 ms, and the message queue call takes 800 ms. The total transaction time is 1.1 seconds. The administrator wants to confirm whether the message queue call is the bottleneck. Which metric would provide the most direct evidence?

   • AThe overall CPU utilization of the tier
   • BThe response time of the message queue exit call
   • CThe number of messages in the queue
   • DThe database call's error rate
