The correct choice is (a) True
Explanation: An aircraft is said to be stable when the aerodynamic forces on the aircraft are equal to thrust produced and the weight of the aircraft. Such a condition is called steady level flight. A highly stable aircraft will return to its initial stable position even if disturbed. Maneuverability is the rate of pitch, roll, and yaw an aircraft can execute without failing. Roll, pitch, and yaw are basically disturbances and a stable aircraft will try to resist the change from its initial position.
