A line through the point A (2, 0), which makes an angle of `30^@` with the positive direction of x-axis is rotated about A in clockwise direction through an angle `15^@`. Then the equation of the straight line in the new position is :

`(2- sqrt3)x+y - 4+2sqrt3=0`

`(2- sqrt3)x-y - 4+2sqrt3=0`

`(2- sqrt3)x-y + 4+2sqrt3=0`

`(2- sqrt3)x+y + 4+2sqrt3=0` .
