Which components are included in the stabilizers of an aircraft?

The correct answer is based on the understanding of the stabilizers and their functions in an aircraft. The stabilizers are crucial components that provide stability and control during flight. They consist of two primary parts: the vertical stabilizer and the horizontal stabilizer.

The vertical stabilizer, located on the aircraft's tail, is responsible for maintaining lateral stability and preventing side-to-side motion (yaw). It typically houses the rudder, which is used for directional control. The horizontal stabilizer is also located at the tail of the aircraft and is responsible for maintaining longitudinal stability, helping to control pitch. This stabilizer usually includes the elevators, which are used to control the aircraft's ascent and descent.

In contrast, other options include components that are either not part of the stabilizers themselves (like propellers and landing gear) or are related to other control surfaces (like ailerons, which control roll and are located on the wings). Recognizing the distinct roles and placements of these components reinforces the importance of understanding the aircraft's design and aerodynamics.
