Which of the following does the FDA NOT regulate?

The FDA does not regulate telecommunications because its jurisdiction primarily covers public health and safety aspects of food, drugs, medical devices, and other related products. Telecommunications is overseen by the Federal Communications Commission (FCC), which manages the country's communications infrastructure including radio, television, and internet services.

In contrast, the FDA plays a significant role in ensuring the safety, efficacy, and security of food products, tobacco products, and medical devices. The agency conducts inspections, evaluates new products, establishes guidelines, and enforces regulations in these areas to protect public health. Thus, recognizing that telecommunications falls outside the FDA's scope is essential for understanding the regulatory framework within which the FDA operates.
