What is the main effect of increased wing area on lift?

Increased wing area is directly related to lift generation due to the fundamental principles of aerodynamics. Lift is produced based on the angle of attack, the shape of the wing, and the airspeed over it, but a larger wing area means that there is more surface available for the airflow to act upon, resulting in greater lift force at a given angle of attack and airspeed.

When the wing area increases, the amount of lift generated can rise even at lower speeds. This is particularly advantageous during takeoff and landing phases of flight when lower speeds are involved, as it allows aircraft to become airborne without needing to reach high velocities. This capability can enhance overall performance, especially for larger or heavier aircraft that require higher lift-to-weight ratios for safe operation.

Other options relate to different aerodynamic principles or operational considerations. Increasing wing area might have implications for drag, but the main effect addressed in the context of lift is the enhanced capability to generate lift at lower speeds.
