The correct option is Lead Time.

The Lead Time widget measures the elapsed time from when a work item is created until it is closed. It reports the total end to end time for an item so you can track delivery speed and trends across work.

Cycle Time is incorrect because it usually measures the time from when work actually starts on an item until it is finished rather than from creation to closure.

Velocity is incorrect because it reports how much work a team completes per iteration or sprint and it does not measure the time to close an individual work item.

Burndown chart is incorrect because it visualizes remaining work over the course of a sprint or iteration and it does not report the total elapsed time for a single work item.
