Answer
- A By the low pressure on the upper surface of the aerofoil
Explanation
The air flows faster over the cambered upper surface, where the pressure drops. On the lower surface there is a slight overpressure. At normal angles of attack, the suction on the upper surface provides the greater part, often about two thirds of the lift.
