@its right is correct

Of the given options, the sentence that best describes the Progressive Era is A: it was a period in which many social reforms occurred.

To arrive at this answer, you can eliminate options C and D as they do not accurately represent the Progressive Era. The Progressive Era did not occur during the Civil War nor was it specifically focused on westward expansion.

Option B can also be eliminated, as the Progressive Era was characterized by efforts to address abuses and corruption by big businesses through regulations and reforms. It was not a period of unchecked abuses by big businesses, but rather a time of social and political activism aimed at improving society.

Ultimately, option A best captures the essence of the Progressive Era, as it was a period in which many social reforms were sought and implemented to address issues such as labor rights, women's suffrage, child labor, and the regulation of monopolistic practices.
