Which of the following can lead to an accelerated stall?

An accelerated stall occurs when the aircraft exceeds its critical angle of attack while in a state of increased load factor or when maneuvering, particularly during abrupt changes in altitude or direction. The sharp pullback on the elevator increases the angle of attack significantly and can cause the wings to reach the critical angle more quickly than during normal flight conditions. This action results in a stall at a higher airspeed than would normally be expected, as the aircraft is subjected to both increased load and the altered airflow over the wings.

In the context of the other options, while a rolling maneuver, excessive bank angle, and landing approaches can contribute to stalls, they are not as directly linked to the concept of an accelerated stall as a sharp pullback on the elevator is. A rolling maneuver and excessive bank angles may create a specific load factor that could lead to a stall, but the immediate and direct action of pulling back sharply on the elevator more rapidly raises the risk of exceeding the critical angle of attack. Landing approaches can also lead to stalls, but they typically do so in a different context, often when the aircraft is configured for landing and at lower airspeeds.
