Can some one please answer this question NO LINKS !!!

How does a wing achieve lift?
1: by forcing air to move faster over the top of the wing
2: by moving air at the same rate on the top and bottom of the wing
3: by forcing air to move slower over the top of the wing

Answer 1

A wing is shaped and tilted so the air moving over it moves faster than the air moving under it. As air speeds up, its pressure goes down. So the faster-moving air above exerts less pressure on the wing than the slower-moving air below. The result is an upward push on the wing—lift!

Answer 2

1: by forcing air to move faster over the top of the wing
