What accurately describes the comparison between stacking and VLT?

VLT allows for more physical devices to appear as one virtual device than stacking does.

Stacked switches share a common control plane while VLT peers maintain their own control plane.

Stacked switches and VLT peers allow “single pane of glass” management by maintaining a single control plane.

Both VLT and stacking allow devices to use different versions of firmware provided that the switch family/ series is the same.
