`Q=(cos (beta-alpha),sin beta)`
and`R=(cos (beta-alpha+theta),sin (beta-theta)`
where `0 lt alpha, beta, theta lt (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

Verified by Experts

The correct Answer is:

D
