CGGO Q17

17Consider the three points, A(3, 6, 4); B(2, 5, 5); C(O, 3, 7) and the view point V(l, 4, 6).
Choose the correct option(s).

Option : D
Explanation :
The equation of the line joining V and A is given by x = t + 3; y = t + 6; z = 4 - t.
Since B and C satisfy this, all the four points are collinear.
We can find that t = 0 for A, t = -1 for B, t = -2 for V and t = -3 for C.
From these values it is clear that these points lie in the order C, V, B, A.
Hence the answer
