Compared with the flap down configuration the maximum angle of attack for the flaps up configuration is
- smaller.
- larger.
- unchanged.
Explanation
This is the reverse view of the flaps-down case. Trailing-edge flaps lower the stalling angle of attack, so removing them (flaps up) gives a larger maximum angle of attack than the flaps-down configuration. The clean wing reaches CLmax at a higher angle than a cambered, flapped wing does.

Could please anyone explain this question?

Another way of asking this question would be:
"What is the effect of flaps on critical angle of attack?"

Because your wing creates more lift with the flaps down, you don't need to as much angle-of-attack to balance the four forces of flight. And because you can fly at a lower angle-of-attack with flaps extended, your stall speed will be lower as well.
