If the vectors `veca,vecb,vecc` form the sides BC,CA and AB respectively of a triangle ABC then (A) `veca.(vecbxxvecc)=vec0` (B) `vecaxx(vecbxvecc)=vec0` (C) `veca.vecb=vecc=vecc=veca.a!=0` (D) `vecaxxvecb+vecbxxvecc+veccxxvecavec0`

A

`veca.vecb+vecb.vecc+vecc.veca=0`

B

`vecaxxvecb=vecbxxvecc=veccxxveca`

C

`veca.vecb=vecb.vecc=vecc.veca`

D
