(C) Given $\vec{A} \cdot \vec{B} = 0$,this implies that $\vec{A}$ is perpendicular to $\vec{B}$ $(\vec{A} \perp \vec{B})$.Given $\vec{A} \cdot \vec{C} = 0$,this implies that $\vec{A}$ is perpendicular to $\vec{C}$ $(\vec{A} \perp \vec{C})$.The cross product $\vec{B} 	imes \vec{C}$ results in a vector that is perpendicular to the plane containing both $\vec{B}$ and $\vec{C}$.Since $\vec{A}$ is perpendicular to both $\vec{B}$ and $\vec{C}$,it must be parallel to the vector $\vec{B} 	imes \vec{C}$.
