Let `vecx, vecy and vecz` be three vectors, each of magnitude `sqrt2` and the angle between each pair of them is `pi/3`. If `veca` is a non-zero vector perpendicular to `vecx and vecy xx vecz` and `vecb` is non-zero vector perpendicular to `vecy and veczxxvecx`, then :

A

`vecb=(vecb*vecz)(vecz-vecx)`

B

`veca=(veca*vecy)(vecy-vecz)`

C

`veca*vecb=-(veca*vecy)(vecb*vecz)`

D

`veca=(veca*vecy)(vecz-vecy)`
