Answer: С
. It led to the passage of food safety regulations like the Pure Food and Drug Act.
Step-by-step explanation:
You included no book and no quote but the above should be the answer because it was an Act that was inspired by public outcry to a book called The Jungle by Upton Sinclair.
The book was based on the unsafe and unsanitary working conditions of immigrants in the meatpacking industry of the US. The public reaction to the book was such that President Theodore Roosevelt sent inspectors to various meat companies and even though these companies tried to clean up, the conditions were still poor.
The United States in response, passed several bills aimed at making food safer such as the Pure Food and Drug Act which laid the foundation for what would later become the Food and Drug Administration (FDA).
