What happens to the DC Primary buses if both DC converters fail?

Explanation:
The key idea is that the DC Primary buses are powered by two independent DC converters. When both converters fail, there is no source feeding those two primary buses, so both of them go dark. The battery and other power paths don’t automatically energize the DC Primary buses, so the system loses power on the first and second DC Primary buses. That’s why the correct outcome is that both the first and second DC Primary buses become unpowered.
