- Correct answer : A — Set an autotermination window on the clusters and update `owned_by` to the team that uses them, so idle time stops accruing and future usage attributes correctly. A . Enforcing autotermination directly removes the root cause of idle spend, and correcting `owned_by` restores accountability so the team responsible can monitor and control the cluster's cost going forward. B . System tables are read-only records generated by the platform from actual account activity; deleting rows from them is not a supported operation and would not stop the underlying cluster from continuing to accrue real charges. C . Raising `min_workers` forces the autoscaler to keep more workers running at all times, which increases baseline cost rather than reducing it, and does nothing to address a cluster that never terminates. D . `system.billing.list_prices` is a reference table of historical SKU rates published by Databricks; it cannot be written to in order to negotiate a lower price, and utilization data has no mechanism to trigger a repricing through this table.
