Which of the following statements about adverse yaw of an airplane is/are correct?
P. It is caused by flow separation resulting from large rudder deflection.
Q. It is caused by dissimilar drag forces acting on the two halves of the wing resulting from aileron deflections of same magnitude.
$\mathrm{R}$. It can be eliminated by ensuring that the upward deflection of one aileron is greater than the downward deflection of the opposite aileron.
(A) P only
(B) Q only
(C) $\mathrm{P}$ and $\mathrm{R}$
(D) $\mathrm{Q}$ and $\mathrm{R}$
