Does lift and drag of an airfoil depend on angle of attack?

A. True

B. False

This question was addressed to me in an online quiz.

This question is from Airfoil Characteristics topic in division Incompressible Flow over Airfoils of Aerodynamics

Right answer is B. False

For explanation I would say: The lift and drag of an airfoil depend not only on the angle of attack but also on the shape of the airfoil. The lift coefficient and drag coefficient depend on the shape of the airfoil and will alter with changes in the angle of attack and other wing appurtenance.
