What section of the united states was the most populous in the antebellum period

i think it could be the south because of all the work the slaves were putting in and all the cotton that was produced along with tabacco and such as that.

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.

the french gave their support to another tribe during he war.
