Suppose That $\vec{u}$ And $\vec{w}$ Both Have Nonzero $y$ And $z$ Components, but Both Also Have Zero

Suppose that $\vec{u}$ and $\vec{w}$ both have nonzero $y$ and $z$ components, but both also have zero $x$ components. Which components of $\vec{q}=\vec{u} \times \vec{w}$ are nonzero? Select or indicate all the letters that apply.

A) $q_{x}$ is nonzero.
B) $q_{y}$ is nonzero.
C) $q_{z}$ is nonzero.
