Let d1 and d2 be parallel lines in the plane. We are marking 11 black points on d1, and 16 white points on d2. We are drawig the segments connecting black points with white points. What is the maximum number of points of intersection of these segments that lies on between the parallel lines (excluding the intersection points on the lines) ?<spanclass=′latex−bold′>(A)</span>5600<spanclass=′latex−bold′>(B)</span>5650<spanclass=′latex−bold′>(C)</span>6500<spanclass=′latex−bold′>(D)</span>6560<spanclass=′latex−bold′>(E)</span>6600
