Which of the foll wing part(s)is used to Steer the airplane while its flying.

Wings & Tail is the correct answer - aircraft steering is achieved through a combination of control surfaces: ailerons on the wings control roll, while the rudder on the vertical stabilizer (tail) controls yaw. The elevators on the horizontal tail stabilizer control pitch. Together, these surfaces allow pilots to steer the aircraft in all three dimensions. Engines provide thrust but don't steer.
