Vector triple product

Unit vector along veca is denoted by hata(if |veca|=1,veca is called a unit vector). Also veca/|veca|=hata and veca=|veca|hata . Suppose veca,vecb,vecc are three non parallel unit vectors such that vecaxx(vecbxxvecc)=1/2vecb [vecpxx(vecxxvecr) is a vector triple product and vecpxx(vecqxxvecr)=(vecp.vecr.vecq)-(vecp.vecq)vecr] . |vecaxxvecc| is equal to (A) 1/2 (B) sqrt(3)/2 (C) 3/4 (D) none of these
