Question 74 of 90 in this shift, Maths question 14 of 30, Section A.

Let the hyperbola H:x2a2−y2b2=1H:\frac{x^2}{a^2}-\frac{y^2}{b^2}=1 pass through the point (22,−22)(2\sqrt{2},-2\sqrt{2}). A parabola is drawn whose focus is same as the focus of H with positive abscissa and the directrix of the parabola passes through the other focus of H. If the length of the latus rectum of the parabola is e times the length of the latus rectum of H, where e is the eccentricity of H, then which of the following points lies on the parabola ?
