I think you forgot to add the options but based on my research the correct answer is "geographic conditions there." The differences in the economic development of the mid-Atlantic, New England, and Southern colonies can BEST be attributed to the geographic conditions there. Thank you for posting your question. I hope that this answer helped you. Let me know if you need more help.

<h3><em><u>From the earliest days of colonial contact, relations between white European settlers and indigenous people in the Americas were plagued by conflict over land and its natural resources. John C. Calhoun, who served as Secretary of War under President James Monroe, was the first to design a plan for removing Native Americans to lands west of the Mississippi River, but the Georgia delegation in the House of Representatives sunk the bill.</u></em></h3>
