JEE Advanced Mathematics question

In each question, match every entry of Column I with the correct entry of Column II. (An entry of Column II may be used more than once.) Column I: (i) The number of sides of the quadrilateral formed by the lines that touch the circle is (ii) are orthogonal unit vectors and . Then equals (iii) A line having direction ratios is perpendicular to the plane , where , and is the origin. Then equals (iv) If the projection of the vector on the vector be then can have the value Column II: (a) (b) (c) (d)

• (1)(i)-(c), (ii)-(a), (iii)-(b), (iv)-(c)Correct
• (2)(i)-(c), (ii)-(a), (iii)-(c), (iv)-(b)
• (3)(i)-(c), (ii)-(c), (iii)-(b), (iv)-(a)
• (4)(i)-(c), (ii)-(b), (iii)-(a), (iv)-(c)
