The correct answer is Time tracking report.

The Time tracking report shows original time estimates alongside time logged and remaining estimates so you can compare planned effort against actual work for a release. Running that report for release 2.0 lets the release manager see, by issue and in aggregate, how close the task estimates were to the time actually spent.

Average age report shows the average age of unresolved issues and helps highlight aging work. It does not show estimated time versus time logged so it will not measure estimate accuracy.

Resolution time report reports how long issues take to be resolved and helps evaluate throughput and response, but it focuses on resolution durations rather than comparing original estimates to actual work.

Version workload report shows how work or issues are distributed across a version and can help with capacity planning, but it does not directly compare original time estimates to logged time so it is not the best report for assessing estimate accuracy.
