The distance from a point (alpha, beta) ...

The distance from a point `(alpha, beta)` to a pair of lines passing through the origin is d. Then the equation to the pair of lines is

A

`(alpha x-beta y)^2=d^2(x^2+y^2)`

B

`(alpha x+beta y)^2=d^2(x^2+y^2)`

C

`(beta x-alpha y)^2=d^2(x^2+y^2)`

D

`(beta x+alpha y)^2=d^2(x^2+y^2)`
