The endpoints of two normal chords of a parabola are concyclic. Then the tangents at the feet of the normals will intersect at
a. Tangent at vertex of the parabola
b. Axis of the parabola
c. Directrix of the parabola
d. None of these

Statement 1: If the endpoints of two normal chords A Ba n dC D (normal at Aa n dC) of a parabola y^2=4a x are concyclic, then the tangents at Aa n dC will intersect on the axis of the parabola. Statement 2: If four points on the parabola y^2=4a x are concyclic, then the sum of their ordinates is zero.
