To determine which geographic region would likely have the highest population density, we can consider general trends regarding population distribution.
A) Piedmont Region: This region often includes urban areas and towns, particularly in the eastern United States, where population density can be high due to proximity to cities like Charlotte, Atlanta, and parts of the Research Triangle.
B) Coastal Plain Region: This area may have some urban locales but also includes more rural and less populated areas, especially in southern portions.
Given these considerations, the Piedmont Region typically has higher population density than the Coastal Plain due to urbanization.
Therefore, the best answer would be:
A) Piedmont Region
