Explanation:

Ida Tarbell was an investigative journalist (muckraker) who wrote about the unethical practices of Standard Oil, which contributed to public outcry and eventually led to the antitrust case that broke up the monopoly. Lincoln Steffens focused on political corruption, Jacob Riis on urban poverty, and Frank Norris on agricultural and railroad monopolies (not Standard Oil).

D. Ida Tarbell
