A vector a of length 2 units is making an angle `60^@` with each of the x - axis and y - axis . If another vector B of length `sqrt(2)` units is making an angle `45^@` with each of the y- axis and Z - axis then `axxb=`

A

`(1-sqrt2)hati-hatj+hatk`

B

`hati-sqrt2hatj+hatk`

C

`sqrt(2) hati -hatj +2hatk`

D

`I - 2 hatj +(1-sqrt2) hatk`
