○ she led a campaign that was against standard oil but in favor of rockefeller
○ she wrote a series of articles exposing the corruption of standard oil.
○ she reported on one instance of suspicious actions by standard oil.

Explanation:

Ida Tarbell was a muckraking journalist. She wrote a series of articles (in "McClure's Magazine") that exposed the unethical and monopolistic practices of Standard Oil, which contributed to public outcry and eventually legal actions against the monopoly. Let's analyze each option:

• First option: She didn't write a book on its impact on different industries in the context of ending the monopoly; her work was more about exposing corruption.
• Second option: She was against Standard Oil and its practices (including those of Rockefeller), not in favor of Rockefeller.
• Third option: Correct, as her series of articles exposed the corruption and monopolistic practices of Standard Oil, leading to increased scrutiny and eventually the breakup of the monopoly.
• Fourth option: She didn't just report on one instance; her work was a comprehensive exposé of multiple unethical actions by Standard Oil.

Answer:

C. She wrote a series of articles exposing the corruption of Standard Oil. (Note: Assuming the options are labeled A, B, C, D with the third option being C as per typical multiple - choice formatting. If the original options had different labels, adjust accordingly based on the actual labeling, but the content of the correct option is "She wrote a series of articles exposing the corruption of Standard Oil".)
