Right choice is (b) False

Easy explanation: There are three planes that can be considered- One immediately ahead of the plane, in plane of the blade and one immediately behind the blade. In case of the plane which is immediately ahead of the blade, the angular velocity is zero resulting in bound and trailing vortices canceling out each other.
