Match the column :

Column I	Column II
(i) If the line 2x + y + 1 + λ(x – y + 1) = 0 is parallel to x axis then λ =	[A] –5
(ii) If the lines x + 2y + 3 = 0, 2x – 3y – 5 = 0, ax – 5ay + 1 = 0 are concurrent then 16a =	[B] –2
(iii) The centroid of the triangle formed by the points (1, a), (2, b) and (c2 , – 3) lie on the x axis then a + b =	[C] 3
(iv) The straight line (x + y + 1) + λ(2x – y – 1) = 0 is perpendicular to 2x + 3y – 8 = 0, then λ is equal to	[D] 5
