A vector `vecn` is inclined to x-axis at `45^(0)`, to y-axis at `60^(0)` and at an acute angle to z-axis. If `vecn` is a normal to a plane passing through the point `(sqrt(2), -1, 1)`, then the equation of the plane is :

A

`4sqrt(2)x+7y+z=2`

B

`sqrt(2)x+y+z=2`

C

`3sqrt(2)x-4y-3z=7`

D

`sqrt(2)x-y-z=2`
