Hydraulics

Hey Guys
can we debate on this question below,i chose the 3rd answer which is PTU but it says it's Electrical Motor rather,why?


With the loss of the system B hydraulic fluid and the system B FLIGHT CONTROL switch to STBY RUD, what allows the movement of trailing edge flaps?
  • A system pressure.
  • Standby hydraulic system pressure.
  • Power Transfer Unit (PTU).
  • Electrical motor
