Problem

Statement I: A ray of light incident at (−3,−1)(-3,-1) gets reflected from the tangent at (0,−1)(0,-1) to the circle x2+y2=1x^2+y^2=1. If the reflected ray touches the circle, then its equation is 4y−3x=54y-3x=5. Statement II: The angle of incidence equals the angle of reflection, that is, ∠i=∠r\angle i=\angle r. (1) Statement I is true, Statement II is true; Statement II is a correct explanation for Statement I. (2) Statement I is true, Statement II is true; Statement II is not a correct explanation for Statement I. (3) Statement I is true, Statement II is false. (4) Statement I is false, Statement II is true.
