If `hat(i) , hat(j) ,hat(k)` are unit vectors alng the positive directin of`x- y-` are z-axis then a false statement in the following is :

A

`Sigma hat(i) (hat(j) + hat(k) ) = 0`

B

`Sigma hat(i) . (hat(j) xx hat(k)) = 0`

C

`Sigma hat(i) xx (hat(j) xx hat(k)) = hat(0)`

D

`Sigma hat(i) xx (hat(j) + hat(k )) = 0`
