Which type of passenger requires a wheelchair for cabin assistance?

The option that identifies a passenger who requires a wheelchair for cabin assistance is the one focusing on a completely immobile individual. This passenger would typically need a wheelchair to navigate from the terminal to the aircraft, and potentially from the aircraft to their final destination within the airport. This is due to their inability to walk or move without assistance, directly indicating that they cannot perform the necessary movements required to access the cabin or maneuver through the airport environment independently.

Passengers who can independently walk or who have the capability to use a cane or possess excellent upper body strength may have varying degrees of mobility that would allow them to manage without a wheelchair. Each situation regarding mobility can differ significantly; therefore, a complete lack of mobility unequivocally requires the use of a wheelchair for assistance during travel.
