How does an aft CG affect the rotation of an aircraft during takeoff?

An aft center of gravity (CG) location can significantly influence the dynamics of an aircraft during takeoff. When the CG is positioned towards the rear, it can cause the nose of the aircraft to lift off the ground before achieving the necessary airspeed for a safe rotation. This premature lift can result in a variety of unsafe conditions, such as the aircraft being unable to achieve the proper angle of attack needed for controlled flight, which is vital during this critical phase.

Moreover, with an aft CG, the control surfaces may also become less effective, making it challenging for the pilot to manage the aircraft's pitch attitude correctly. Thus, it's crucial to maintain a balanced CG within the aircraft's specified limits to ensure a safe and effective takeoff process. The other choices do not accurately reflect the aerodynamic relationships inherent to an aft CG scenario during takeoff. Stability and fuel consumption are generally not directly related to an aft CG in a takeoff scenario, while premature stalling is a more complex phenomenon that is not solely attributed to CG positioning.
