Consider the parabola y = 4x. Let S be the focus of the parabola. A pair of tangents drawn to the parabola from the point P = (-2, 1) meet the parabola at P and P. Let Q and Q be points on the lines SP and SP respectively such that PQ is perpendicular to SP and PQ is perpendicular to SP. Then, which of the following is/are TRUE? (A) SQ = 2 (C) PQ =3 (B) (D) QQ SQ = 1 = 310 5
