Final answer:
The Fall Line became more important to Georgians because of its potential for hydroelectric power, which was pivotal to the state's industrialization.
Step-by-step explanation:
The Fall Line in Georgia became more important as the state industrialized primarily due to its potential for hydroelectric power. As Georgia and other southern states began to transition from an agricultural-based economy to one that incorporated more industrial activities, the waterfalls and rapids along the Fall Line provided the perfect site for harnessing water power, which could then be used to run factories and mills. Thus, the correct answer to the student's question would be option b) Due to its potential for hydroelectric power.
