B. Turn on concurrency scaling at the workload management (WLM) queue level in the Redshift cluster. Explanation: Concurrency scaling in Amazon Redshift allows the cluster to automatically add and remove compute resources in response to workload demands. Enabling concurrency scaling at the workload management (WLM) queue level allows you to specify which queues can benefit from concurrency scaling based on the query workload.

B"You can manage which queries are sent to the concurrency-scaling cluster by configuring WLM queues. You're charged for concurrency-scaling clusters only for the time they're actively running queries." https://docs.aws.amazon.com/redshift/latest/dg/concurrency-scaling.html
