The correct answer is (a) True

Best explanation: Down wash is the change in direction of air deflected by the aerodynamic action of an airfoil, wing, or helicopter rotor blade in motion, as part of the process of producing lift. When the relative wind moves from nose to down side of the wing which causes change in direction of air and produce lift.
