Step-by-step explanation:
Aircraft batteries can run for a certain amount of time depending on the condition and whether the XFER buses are on or off.
Option B) states that aircraft batteries can run for 45 minutes with XFER buses off within 30 minutes.
This means that without the XFER buses on, the batteries can power the aircraft for 45 minutes, but if the XFER buses are turned on, the batteries will only last for 30 minutes.
