Answer:
C. Muckrakers were journalists who sought to expose scandals in business and politics.
Step-by-step explanation:
Muckraking is a term most commonly associated with the profession of journalism especially during the late 19th and early 20th centuries. The writers/ journalists of this time wrote about the major corruptions in the political as well as economical world.
The literal use of the word "muckrakers" was first applied by Theodore Roosevelt, based from John Bunyan's "Pilgrim's Progress" where a man was described with a muckrake in his hands, looking only downwards and nowhere else. This is symbolic for muckrakers are those workers who cleaned the muck with a rake, and are indispensable for the cleaning of the worse 'dirt'.
These journalists are then labelled or referred to be "muckrakers" in their work of exposing scandals in the business as well as the political sphere.
