The vertex A of triangle ABC is on the line vector r = i + j + λk and the vertices B & C have respective position vectors i and j . Let Δ ∈[3/2, √33/2] be the area of the triangle and , then the range of values of λ corresponding to A is
(a) [–8, –4] ∪ [4,8]
(b) [–4,4]
(c) [–2,2]
(d) [–4,–2]∪ [2,4]
