Is airfoil shape similar to blades of the propeller?

(a) True

(b) False

I had been asked this question during an interview.

This is a very interesting question from Airfoil Characteristics topic in chapter Incompressible Flow over Airfoils of Aerodynamics

Correct choice is (a) True

For explanation I would say: An airfoil is the shape of a wing, blade of a propeller, rotor, and blades of a turbine. A propeller is a type of fan that transmit power by converting rotational motion in its thrust.A  pressure difference is produced between the forward and rear surface of the airfoil-shape and fluid is accelerated behind the blade.
