A
$x =- 2, y = -3$

B
$x = 2, y = - 3$

D
$x =4, y = 3$

E
$x =3, y = 4$

Solution:
We have equation of hyperbola is
$x y+3 x-2 y-10=0$
$x y+3 x-2 y-6=4$
$(x-2)(y+3)=4$
We know that asymptote of hyperbola
$x y=c$ is $x=0$ and $y=0$.
$\therefore $ Asymptote of hyperbola
$(x-2)(y+3)=4$ is $x-2=0, y+3=0$
$\Rightarrow x=2, y=-3$
