If angle of attack is increased beyond th e critical angle of attack, the lift coefficient ... and the stagnation point moves...
- decreases; rearward
- increases; rearward
- decreases; forward
Explanation from PART66Online
Beyond the critical angle of attack the airflow separates from the upper surface, so the lift coefficient falls away in the stall. As angle of attack increases the forward stagnation point migrates rearward along the lower surface, away from the leading edge.

Is this a typo? Shouldn't this be seperation point? Stagnation point is infront of the leading edge, it can only move up and down not forward and back.

when it moves up and down it moves slightly fwd or aft a little bit
