b. False
Explanation: Engines (propellers or jets) provide thrust to move the airplane forward. Lift, produced by the wings as air moves over them, is what actually raises the aircraft off the ground. (Exceptions exist for VTOL aircraft and helicopters, which use engines/rotors to produce vertical lift.)
