Answer

Brief Explanations:

John D. Rockefeller dominated the oil industry by creating a monopoly. He bought up most of the oil refineries (option C). Option A is incorrect as creating new products doesn't directly lead to industry domination. Option B is not accurate as his methods were more about monopoly through acquisitions. Option D is wrong as he focused on domestic refineries and control, not foreign oil supply.

Answer:

C. He bought up most of the oil refineries to create a monopoly.
