The correct answer is (a) True

For explanation: For a lifting wing, the air pressure on the top of the wing is lower than the pressure below the wing. The tip of the wing, the air is free to move from the region of high pressure into the region of low pressure. The resulting flow at the left by the two circular blue lines with the arrowheads of flow direction.
