Answer:
Option E. Elimination of as much competition as possible.
Step-by-step explanation:
Following the American Civil War, big business and corporations started to flood the US market.
Ohio's Standard Oil Company was one of the most famous monopolies in US history, entirely dominating the oil market in the Eastern and middle sections of the country. By completely eradicating the competition, the company could have full control over prices, demand, labor wages and productions of the asset.
