When the trailing edge flaps are lowered, the aircraft will
- pitch nose up.
- pitch nose down.
- yaw to one side.
Explanation
Lowering the trailing-edge flaps increases camber and moves the centre of pressure rearward, producing a nose-down pitching moment, so the aircraft tends to pitch nose down. This is a pitch change about the lateral axis, not a yaw, and the pilot trims it out.

how come?

I think it will pitch nose down because centre of pressure moves aft.

Flaps move the center of pressure of the wing more rearward. Since the CG stays put, this produces a more nose down pitching moment which improves the pilot's view of the runway over the nose of the aircraft during landing.
However, the flaps may also cause pitchup, depending on the type of flap and the location of the wing.

If trailing edge flaps are lowered,it is functioning like elevator.
