What effect does lowering flaps for takeoff have?
- Reduces takeoff speeds only.
- Reduces the landing speed only.
- Reduces both takeoff and landing speeds.
Explanation from PART66Online
Selecting flap for take-off raises the maximum lift coefficient, so the wing reaches the required lift at a lower speed, shortening the take-off run. The question concerns the take-off case, so the reduction applies to take-off speed; landing speed is a separate selection not in scope of this take-off scenario.

Because ATA 27 takeoff flap setting is a small deflection and is retracted shortly after climb-out, answer is A. Landing uses a different and fuller flap position, so the takeoff config does not influence the eventual landing speed.

And the question is asking about takeoff.
