Match the column
| Column - I | Column – II |
| (A) If vector a, b, c are three mutually perpendicular vectors where |vector a| = |vector b| = 2 and |vector c| = 1, then 1/12 [vector (a x b b x c c x a)] is | (p) - 3/4 |
| (B) If vector a, b are two unit vectors inclined at π/3, then [vector a b + a x b b] is | (q) 0 |
| (C) If vector a, b are orthogonal unit vectors and vector b x c = a, then [vector (a + b + c a + b b + c)] is | (r) 4/3 |
| (D) If [vector x y a] = [vector x y b] = [vector a b c] = 0 each vector being a () 1 non-zero vector, and no two vectors are collinear then [vector x y c] = | () 1 |
