Correct answer is (a) lift curve slope vs mach number

Easiest explanation: The above diagram is showing a typical variation between lift curve and Mach number. Drag polar is nothing but the drag variation with lift or angle of attack. It is used to estimate drag properties of airfoil and wing. Wing loading is defined as the ratio of weight to the reference area.
