When the trailing edge flap is extended
- CP moves rearward.
- the CP moves forward.
- the CP remains stationary.
Explanation
Extending a trailing-edge flap adds camber and lift concentrated toward the rear of the chord, which moves the centre of pressure rearward. The aft shift in the lift point also produces a nose-down pitching moment, one reason flap extension is usually accompanied by a trim change.

Regarding the above question the CP moves forward in basic single engine aircraft and CP moves rearward in high speed aircraft where mach tuck happens so the question should specify it?

Hello!
As I know, with flaps extended center of pressure moves rearward. But I'm not expert, maybe someone can provide proof link? I googled that and found what this question is very very wide, but basically with extended flaps CP moves rearward.
