If these are the missing choices:
The diverse geography of the colonies encouraged different economic pursuits.
The geography of the colonies had little influence on the economies that developed.
Most of the colonies developed similar economies because they all had similar geography.
All of the colonies benefited from good soil and a long growing season.
My answer is:
The diverse geography of the colonies encouraged different economic pursuits.
The economy of each colony is dependent on its geographic location and its weather conditions. They have to live off the resources of the land to ensure their survival. Diversity is present among these colonies because one economic pursuit can't be applicable to another colony unless they share the same characteristics that the other colony have.
