Final answer:
The map shows that Napoleon's empire controlled most of Europe in 1812.
Step-by-step explanation:
According to the map, Napoleon's empire controlled most of Europe in 1812. The map shows France in 1799 and the land added to Napoleon's empire by 1812, including countries that were allied with his empire. While there were some major ports that Napoleon had lost control of due to the dominance of the British navy, this does not diminish the fact that Napoleon controlled most of Europe at that time. Therefore, the statement that best describes Napoleon's empire based on the map is that he controlled most of Europe.
