Question
A ray of light through $(2,1)$ is reflected at a point $P$ on the $y$-axis and then passes through the point $(5,3)$. If this reflected ray is the directrix of an ellipse with eccentricity $\frac{1}{3}$ and the distance of the nearer focus from this directrix is $\frac{8}{\sqrt{53}}$, then the equation of the other directrix can be :
Select the correct option:
A
11x + 7y + 8 = 0 or 11x + 7y – 15 = 0
B
11x – 7y – 8 = 0 or 11x + 7y + 15 = 0
C
2x – 7y + 29 = 0 or 2x – 7y – 7 = 0
D
2x – 7y – 39 = 0 or 2x – 7y – 7 = 0
