"Dashboard > Status > System Information".
The guide describes the "System Information" widget. It specifies that the "Firmware Version" field displays the currently running firmware. It also explains that the "Firmware" section with "Current" and "Previous" partitions shows the active and inactive firmware images
confirming that the existence of a "Previous" version implies an upgrade has occurred. The "Disk Usage" section is described as showing the percentage of the hard disk that is used. This directly supports the correctness of B and D
and the incorrectness of A and C.
