The correct answer is:
Either $\vec{a}$ or $\vec{b}$ is a null vector
Let $\vec{a}$ and $\vec{b}$ are two vectors such that $\vec{a} \cdot \vec{b}=0$ and
$\vec{a} \times \vec{b}=0$ then either $\vec{a}$ or $\vec{b}$ is a null vector.
$\vec{a} \times \vec{b}=0$ then either $\vec{a}$ or $\vec{b}$ is a null vector.
