The Correct Option is A

Solution and Explanation

Step 1: Define Aerodynamic Center.
The aerodynamic center of an airfoil is the point at which the pitching moment coefficient does not vary with changes in the angle of attack, at least over a practical range of angle of attack.
Step 2: Significance of the Aerodynamic Center.

This characteristic allows the aerodynamic center to be a critical point for analyzing and designing aircraft stability and control because stability about the aerodynamic center remains consistent regardless of small changes in angle of attack.
