If vectors `veca and vecb` are non collinear then `veca/(|veca|)+vecb/(|vecb|)`

If vectors `veca and vecb` are non collinear then `veca/(|veca|)+vecb/(|vecb|)` is (A) a unit vector in the plane of `veca and vecb` (B) in the plane of `veca and vecb` (C) equally inclined ot vecas and vecb` (D) `perpendiculat to `veca xx vecb`
