If a variable tangent of circle x2 + y2 = 1 intersects the ellipse x2 + 2y2 = 4 at points P and Q, then the locus of the point of intersection of tangents at P and Q is (a) a parabola with latus rectum = 4 (b) a parabola with focus as (2, 3) (c) an ellipse with eccentricity (d) an ellipse with eccentricity greater than ½.
