Let $P Q$ be a focal chord of the parabola $y^2=36 x$ of length 100 , making an acute angle with the positive $x$-axis. Let the ordinate of $P$ be positive and $M$ be the point on the line segment $P Q$ such that $P M$ : $M Q =3: 1$. Then which of the following points does NOT lie on the line passing through M and perpendicular to the line PQ ?
