A triangle is formed by the lines whose combined equation is given by (x+y-4)(x y-2 x-y+2)=0. The equation of its circumcircle is

• A

  ${\mathrm{x}}^2+{\mathrm{y}}^2-5\mathrm{x}-3\mathrm{y}+8=0$

• B

  ${\mathrm{x}}^2+{\mathrm{y}}^2-3\mathrm{x}-5\mathrm{y}+8=0$

• C

  ${\mathrm{x}}^2+{\mathrm{y}}^2+2\mathrm{x}+2\mathrm{y}-3=0$

• D

  None of the above
