## Question

### Solution

Correct option is

The line through Q parallel to y-axis

Let the coordinates of P, Q, R be (ati2, 2ati)i = 1, 2, 3 having ordinates in G.P. So that t1t2t3 are also in G.P. i.e. t1t3 = t22. Equations of the tangents at P and R are

ty = x + at12 and t3 y = x + at32, which intersect at the point Which is a line through Q parallel to y-axis.
