The correct response highlights a fundamental aspect of aerodynamics concerning the behavior of the center of pressure in relation to the angle of attack. As the angle of attack of an airfoil increases, the center of pressure, which is the point where the resultant lift force acts, initially moves forward. This shift occurs because the increased angle of attack generates greater lift, and the distribution of pressure over the airfoil's surface changes accordingly.

When approaching the stall point, this forward movement of the center of pressure continues until it reaches a critical angle where the airflow begins to separate from the upper surface of the wing, leading to a stall. At this moment, the center of pressure shifts rapidly rearward, as the lift starts to diminish significantly due to the loss of effective airflow over the wing. This behavior is crucial for pilots to understand, as it plays a vital role in handling the aircraft during various flight maneuvers, especially during high angles of attack, to avoid unintentional stalls.

The other options do not accurately describe the behavior of the center of pressure with increases in angle of attack. For instance, stating that it remains static would overlook the dynamic changes induced by airflow conditions. Saying it shifts backward continuously fails to consider the initial forward movement and the stall
