If `x=9` is the chord of contact of the hyperbola `x^2-y^2=9` then the equation of the corresponding pair of tangents is (A) `9x^2-8y^2+18x-9=0` (B) `9x^2-8y^2-18x+9=0` (C) `9x^2-8y^2-18x-9=0` (D) ` `9x^2-8y^2+18x+9=0`

A

`9x^(2)-8y^(2)+18x-9=0`

B

`9x^(2)-8y^(2)+18x+9=0`

C

`9x^(2)-8y^(2)-18x-9=0`

D

`9x^(2)-8y^(2)+18x+9=0`
