(a) By looking at the figure, explain why the number of shortest routes from A to D, C(9, 3), plus the number of shortest routes from A to E, C(9, 4), should equal a single combination, C(10, 4). Choose the correct answer below. OA. All combinations from A to B pass through point C. OB. The two points where the combinations stop are the two points that make up the intersection of B. OC. The two points where the combinations stop are two of three of the points that make up the intersection of B. OD. The only routes from A to B are contained in these two combinations.
