B) Savannah River - The Savannah River does form part of the boundary between Georgia and South Carolina, but it does not serve as most of the boundary. In addition, it does not flow through the Piedmont and Coastal Plain regions. The Savannah River is not the correct answer.

C) Ocmulgee River - The Ocmulgee River does not form Lake Hartwell, and it does not serve as the boundary between Georgia and South Carolina. Therefore, it is not the correct answer.

D) Chattahoochee River - The Chattahoochee River does serve as most of the boundary between Georgia and Alabama, which is part of the Georgia-South Carolina boundary. It also forms Lake Hartwell in eastern Georgia. Moreover, the Chattahoochee River flows through both the Piedmont and Coastal Plain regions. Therefore, the correct answer is D) Chattahoochee.
