Which chart displays the average number of queued SQL statements in each consumer group?

The choice that accurately represents the average number of queued SQL statements in each consumer group is the one that explicitly indicates queued statements. This specific chart provides a direct visualization of how many SQL statements are waiting to be executed in each consumer group, which is critical for understanding resource contention and performance issues in a database environment.

The representation of queued statements allows database administrators to monitor and optimize workload distribution effectively. Understanding how many statements are queued gives insights into the efficiency of resource utilization and helps in identifying potential performance bottlenecks.

In contrast, the other options focus on different aspects of SQL statement monitoring. For instance, charts showing running SQL statements or average SQL statement response time might provide useful information about currently executing statements or their performance metrics but do not specifically quantify the number of statements that are queued. Therefore, they do not fulfill the requirement of displaying the average number of queued SQL statements in each consumer group.
