Hi
Answer C. The landing gear lever has to be selected to the 'OFF' position to move the landing gear selector valve into a position to prevent a hydraulic lock of the landing gear whilst under free-fall during the manual extension.

I'll have a stab.
In OFF position hyd pressure (or just fluid if no pressure) is ported to 'return' in both retract and extend hyd circuits.This would allow as much freedom as possible for manual extension.
After down and locked, select down cos that is where you want your wheels to be and stay.
It also inhibits any lights / warnings by not having the gear in position selected, ie normal config
