Answer:
C) Below the fall line, water flows into the mountains.
Step-by-step explanation:
The fall line is a geological boundary, moving across Georgia from Columbus to Augusta.
The fall line in Georgia is responsible for water flows into the mountains below the fall line because below the fall line the elevation decreases from the north to the south and leads to water flows into the mountains.
Hence, the correct answer is "C) Below the fall line, water flows into the mountains."
