136- In rectangle $ABCD$, point $(5,3)$ is vertex $B$ and the lengths of sides $C$ and $D$ are $5/8$ and $3$ respectively. If vertex $D$ is reflected over the $x$-axis, the distance from the image of vertex $C$ to the line $BD$ from the origin of coordinates is how much?
\[ \text{(1)}\ 2/5 \qquad \text{(2)}\ \sqrt{6/5} \qquad \text{(3)}\ \sqrt{6} \qquad \text{(4)}\ 2 \]
