Let γ ∈ ℝ be such that the lines L₁ : (x + 11)/1 = (y + 21)/2 = (z + 29)/3 and L₂ : (x + 16)/3 = (y + 11)/2 = (z + 4)/γ intersect. Let R₁ be the point of intersection of L₁ and L₂. Let O = (0, 0, 0), and n^ denote a unit normal vector to the plane containing both the lines L₁ and L₂. Match each entry in List-I to the correct entry in List-II. List-I: (P) γ equals, (Q) a possible choice for n^ is, (R) OR₁⃗ equals, (S) a possible value of OR₁⃗ · n^ is. List-II: (1) −î − ĵ + k^, (2) √(3/2), (3) 1, (4) (1/√6)î − (2/√6)ĵ + (1/√6)k^, (5) √(2/3). The correct option is
