The answer is b.) The diverse geography of the colonies encouraged different economic pursuits.
Since the colonies of the north had different climate and resources than those of the south, the economy and the way of life were also affected, which in turn led to different policies even when the United States was already a free country. The most notorious example would be cotton plantations in the southern colonies, such as Virgina and South Carolina, where settlers needed slaves to run the crop economy, and that in turn, decades later, caused the division of the North and the South in the American Civil War.
