Explanation:In the chart, we can mark the points that represent 4X4 regions with number 1 to 4, and mark sub-points of point 1 with number 1-1 to 1-4, and so on and so forth. The corresponding positions of regions in the map and points in the chart are shown as below. 1-3, 1-4, 2-3 and 2-4 are marked in black in the chart, which means that the colour of these four 2X2 regions in the map is black. Only (B) satisfies this criteria.
