Answer: Cluster Event Log
The Cluster Event Log (Option D) is the correct answer because it specifically records detailed events related to the lifecycle of a Databricks cluster, including autoscaling actions like node additions or removals. This log provides a timeline of resizing events, which helps administrators correlate scaling activities with user concurrency or query resource demands. Workspace audit logs (A) track administrative actions but not cluster-level scaling events. The driver's log file (B) contains Spark application logs, not cluster management details. Ganglia (C) focuses on resource utilization metrics but does not explicitly log cluster resizing decisions.
