Best answer
Right choice is (a) True

Explanation: The total drag is the sum of pressure drag and induced drag. The correct equation is D=YVe^e+\(\frac{ZW^2}{V^2_e}\) where where Y is a constant, V is velocity, W is weight, V is velocity, Z is constant and D is total drag. The total drag is the sum of pressure drag and induced drag.
