During the 1500s and 1600s, the slave trade to north america differed from the slave trade to the caribbean because a. slavery was made illegal in north america after the 1580s b. more enslaved africans were sent to north america than to the caribbean c. more enslaved women were sent to north america than to the caribbean d. slavery in the caribbean was more self-sustaining than it was in north america

i think the answer is c, rivers.

explanation:

sometimes, borders fall along natural boundaries like rivers or mountain ranges. for example, the boundary between france and spain follows the crest of the pyrenees mountains. for part of its length, the boundary between the united states and mexico follows a river called the rio grande. the borders of four countries divide africa’s lake chad: niger, chad, cameroon, and nigeria.
