Q1 this is mcqs only need correct option with little explanation to make sure its correct..but as soon as possible

QUESTION 1 Not yet answered The lines Marked out of 100 L1: x = (-1, -4) + p1 (1, 3) Flag and question L2: x = (2, 3) + p2 (1, 1), where p1, p2 E R, intersect. Find the parametric equation of the line L3 which passes through the point of intersection of L1 and L2 and is perpendicular to L1. (A) x = (1, 2) + t(3, -1), where t E R (B) x = (2, -1) + t(3, -1), where te R (C) x = (1, 2) + t(-1, 3), where the R (D) x = (1, 2) + t (3, 1), where the R (E) x1 + 3.12 = 7
