The combined equation of the two lines $$ax + by + c = 0$$ and $$a'x + b'y + c' = 0$$ can be written as $$(ax + by + c)(a'x + b'y + c') = 0$$. The equation of the angle bisectors of the lines represented by the equation $$2x^2 + xy - 3y^2 = 0$$ is

A

$$3x^2 + 5xy + 2y^2 = 0$$

B

$$x^2 - y^2 + 10xy = 0$$

C

$$3x^2 + xy - 2y^2 = 0$$

D

$$x^2 - y^2 - 10xy = 0$$
