The equation of the incircle of the triangle formed by the coordinate axes and the line 4x + 3y - 6 = 0 is

(A) `x^(2) + y^(2) - 6x - 6y - 9 = 0 `
(B) ` 4 (x^(2) + y^(2) - x - y) + 1 = 0 `
(C) ` 4 (x^(2) + y^(2) + x + y) + 1 = 0 `
(D) ` 4 (x^(2) + y^(2) - x - y ) - 1 = 0 `

A

`x^(2) + y^(2) - 6x - 6y - 9 = 0 `

B

` 4 (x^(2) + y^(2) - x - y) + 1 = 0 `

C

` 4 (x^(2) + y^(2) + x + y) + 1 = 0 `

D
