Consider three points $P = ( - \sin ( \beta - \alpha ) , - \cos \beta ) , Q = ( \cos ( \beta - \alpha ) , \sin \beta )$ and $R = ( \cos ( \beta - \alpha + \theta ) , \sin ( \beta - \theta ) )$, where $0 < \alpha , \beta , \theta < \frac { \pi } { 4 }$. Then,\\
(A) $P$ lies on the line segment $R Q$\\
(B) $Q$ lies on the line segment $P R$\\
(C) $R$ lies on the line segment $Q P$\\
(D) $P , Q , R$ are non-collinear
