Tangents are drawn to the circle x^2 + y...

Tangents are drawn to the circle `x^2 + y^2 = 32` from a point `A` lying on the x-axis. The tangents cut the y-axis at points `B and C`, then the coordinate(s) of `A` such that the area of the triangle `ABC` is minimum may be: (A) `(4sqrt(2), 0)` (B) `(4, 0)` (C) `(-4, 0)` (D) `(-4sqrt(2), 0)`
