The correct answer is A. Gold was discovered on Cherokee lands.
Step-by-step explanation
During the first half of the 18th century in the United States, Amerindian peoples of the western United States such as the Choctaw and the Cherokee were victims of a massive exile from their lands due to the Gold Rush that began at this time. This problem became more intense during the 1930s as gold speculators began to put pressure on the state government to exploit the gold that had been found in the Cherokee territory in Georgia. According to the above, the correct answer is A. Gold was discovered on Cherokee lands.
