A square of side 2 units lie above the `x` -axis and has one vertex at the origin. The side passing through the origin makes an angle `30^(circ)` with the positive direction of `x` -axis. The equation of its diagonal not passing through the origin is

A

`(sqrt(3)+1) y+(sqrt(3)-1) x=4`

B

`(sqrt(3)-1) y-(sqrt(3)-1) x=4`

C

`(sqrt(3)+1) y-(sqrt(3)-1) x=4`

D

`(sqrt(3)+1) y+(1+sqrt(3)) x=4`
