The centroid (point where medians intersect) divides each median into two segments, one of which is twice the length of the other. The longer segment, from the vertex to the centroid, is two-thirds the length of the entire median. The median from vertex A(3, 4) to the midpoint of the opposite side (which is the midpoint of (0, 0) and (8, 0), i.e., (4, 0)) has a length found using the distance formula: $\sqrt{(3-4)^2 + (4-0)^2} = \sqrt{1^2 + 4^2} = \sqrt{17}$. Two-thirds of this distance is $\frac{2}{3} \sqrt{17}$, which matches choice C.
