The correct answer is A) to bring financial support.
Workers from eastern states were encouraged to come to Oklahoma during the early oil boom to bring financial support.
For instance, Robert M. Darden was one of the first oilmen. He came from the state of Missouri to Oklahoma to organize the first company that extracted oil in 1872. It was called the Chickasaw Oil Company. In 1884, H. W. Faucett opened the Choctaw Oil and Refining Company and he also was prosperous enough to open the Cherokee Oil Company.
