Final answer:
The map with the scale 1:4,000,000 would display the most area of land.
Step-by-step explanation:
The map that would display the most area of land is the one with the smallest scale, which means that each unit on the map represents a larger area in real life. The scale is represented by the numbers after the colon. So, out of the options given, the map with the scale 1:4,000,000 would display the most area of land because each unit on the map represents a larger area.
