A straight line through the vertex P of ...

A straight line through the vertex `P` of a triangle `PQR` intersects the side `QR` at the point `S` and the circuecirele of the triangle `PQR` at the point `T.` If `S` is not the centre of the circumeircle, then

A

`(1)/(PS) +(1)/(ST)lt (2)/(sqrt(QSxxSR))`

B

`(1)/(PS) +(1)/(ST) gt(2)/(sqrt(QSxxSR))`

C

`(1)/(PS) +(1)/(ST) lt (4)/(QR)`

D

`(1)/(PS)+ (1)/(ST) gt (4)/(QR)`
