Problem

For two particular vectors

\mathbf{A}

and

\mathbf{B}

, it is known that

\mathbf{A} \times \mathbf{B} = \mathbf{B} \times \mathbf{A}

. What must be true about the two vectors? a. At least one of the two vectors must be the zero vector b.

\mathbf{A} \times \mathbf{B} = \mathbf{B} \times \mathbf{A}

is true for any two vectors c. One of the two vectors is a scalar multiple of the other vector d. The two vectors must be perpendicular to each other
