A mirror and a source of light are situated at the origin `O` and at a point on `O X ,` respectively. A ray of light from the source strikes the mirror and is reflected. If the direction ratios of the normal to the plane are `1,-1,1,` then find the `D C s` of the reflected ray.

A

B

`(1)/(3), (2)/(3), (2)/(3)`

C

`-(1)/(3), -(2)/(3), -(2)/(3)`

D
