From an arbitrary point P on the circle ...

From an arbitrary point `P` on the circle `x^2+y^2=9` , tangents are drawn to the circle `x^2+y^2=1` , which meet `x^2+y^2=9` at `A` and `B` . The locus of the point of intersection of tangents at `A` and `B` to the circle `x^2+y^2=9` is
(a) `x^2+y^2=((27)/7)^2` (b) `x^2-y^2((27)/7)^2` (c) `y^2-x^2=((27)/7)^2` (d) none of these
