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 RQ

B

Q lies on the line segment PR

C

R lies on the line segment QP

D

P, Q, R are non-collinear
