Refer to the exhibit.

In the exhibit, the status indicators show:

AC (Alternating Current):A green light indicating the PowerScale system is receiving power from the AC input, which means it is powered on.

DC (Direct Current):The absence of a lit DC indicator means that the system is not currently converting AC power to DC power, but this does not indicate an issue with functionality based on this view.

Given that the AC light is green, the system is powered and functioning as expected. Therefore, the system is "On and healthy" based on the AC input, makingB. On and healthythe correct answer.
