The line $\frac{x}{3}+\frac{y}{2}=1$ and a pair of lines both passing through the origin form an isosceles triangle. If this pair of lines are perpendicular,then the equation of the pair of straight lines is

  • A
    $5\left(x^2-y^2\right)+24 x y=0$
  • B
    $5\left(x^2-y^2\right)-24 x y=0$
  • C
    $5\left(x^2-y^2\right)+12 x y=0$
  • D
    $5\left(x^2-y^2\right)-12 x y=0$
