Orthogonal vectors have a dot product of zero. Therefore, we can find the dot product of u and v and check if it is zero. If it is, then u and v are orthogonal. If not, then they are either parallel or neither. Without knowing the actual values of u and v, it is impossible to determine whether they are parallel or neither, so option C cannot be the answer.
