The correct answer is B) reforming the tax system.

The Progressive movement took place during the early 20th century in American history. This political group focused on reforming different parts of American society, including the tax system. The Progressives believed in a progressive tax rate. This means that individuals who are wealthy pay a higher percentage in taxes than individuals who are poor. This concept is based on the idea that rich citizens can afford to pay more taxes than someone who comes from a lower socioeconomic status.
