(D) In a regular hexagon $ABCDEF$ with center $O$,the vector $\vec{AO}$ represents the directed line segment from the center $O$ to the vertex $A$. By the properties of a regular hexagon,the vector $\vec{AO}$ is equal to the vector $\vec{ED}$ and $\vec{BC}$. Looking at the options provided,$\vec{BC}$ is not explicitly listed,but we can analyze the vectors given. Note that $\vec{AO} = \vec{ED} = \vec{BC}$. Since $\vec{BC}$ is not an option,let us re-examine the geometry. Actually,$\vec{AO} = \vec{ED}$ is correct. Thus,the vector $\vec{AO}$ is equal to $\vec{ED}$.

Let $ABCDEF$ be a regular hexagon with the vertices $A, B, C, D, E, F$ in counter-clockwise order. If $O$ is the center of $ABCDEF$,then the vector $\vec{AO}$ is equal to which of the following?
