Doubling the incidence of a supersonic wing at fixed Mach number changes its wave drag due to lift by a factor of
Answer: C
Wave drag due to lift varies with the square of the lift coefficient, and by linearised theory the lift coefficient is proportional to incidence, so doubling the angle multiplies that drag component by four. The volume-dependent part is unaffected, since it depends on thickness alone.
