A and C
I seem to remember that one of the several forces producing yaw during take off is that due to gyroscopic precession. This force will produce yaw when the nose is raised (or lowered). Its magnitude is proportional to the amount of angular momentum the rotating mass has hence a radial engine (which has a greater rotating mass) makes the effect more noticeable than with a "normal" a/c.
I've got a feeling that the effect is seen as a right hand swing when the tail of a taildragger is raised.
