The speed of air over a swept wing which contributes to the lift is
- less than the aircraft speed.
- the same as the aircraft speed.
- more than the aircraft speed.
Explanation from PART66Online
On a swept wing only the airflow component perpendicular to the leading edge (the chordwise component) accelerates over the section and produces lift. Because the wing is swept, this effective component is less than the full free-stream speed, so the speed contributing to lift is lower than the aircraft's airspeed.

isnt upper surface has more velocity than the relative wind?

If aircraft speed is V, speed of airflow over wing which contributes to lift is Vcos(sweepangle). Cos(sweepangle) < 1
