D.After the American Revolution, the United States achieved political stability. After the Mexican War of Independence, Mexico suffered continued instability.
I believe the answer is D but I'm not 100% sure, I know that after the American Revolution the united states adopted the political standpoint of an independent country and not a split opinion between the US being an independent party and rejoining with Great Britain, but I'm not sure what happend with Mexico after their war for independence.
