Where does the hydraulic pump 3B receive its power?

Explanation:
Hydraulic pump 3B is electric and designed with dual power sources for redundancy. It can be powered from AC Bus 1 during normal operation, and from the Air Driven Generator (ADG) to keep essential systems alive if electrical power from the engines is lost. Because it’s wired to both sources, it can receive power from either one, ensuring the pump keeps running under different failure scenarios. The other options don’t fit because the pump is not engine-driven, and it isn’t limited to a single source.
