  1. Four, including the pilot
  2. Three, including the pilot
  3. Two, including the pilot ✔

Why: After MOSAIC, sport pilots may fly airplanes with up to four seats. They are still limited to one passenger, so two occupants total, including the pilot.

Huh, didn't know that: MOSAIC lets the aircraft be bigger, but the sport pilot's own passenger limit did not change.
