Two modes are available for deleting scaling groups in Auto Scaling: ForceDelete mode and non-ForceDelete...

In non-ForceDelete mode, a scaling group can only be deleted if no ECS instances exist within it and no scaling activities are currently in progress. This ensures that resources are properly released and no scaling operations are disrupted during deletion. Scheduled and event-triggered tasks (option C) and SLB/RDS integrations (option D) do not need to be removed to delete the scaling group in non-ForceDelete mode.
