The correct choice pertains to Parts 171-180 of the Code of Federal Regulations (CFR), which specifically govern the transportation of hazardous materials. This section outlines comprehensive guidelines and regulations that must be followed to ensure safe and compliant transportation practices.

These parts cover a variety of topics, including definitions, classification, packaging, labeling, and handling of hazardous materials. They serve to protect public safety, health, and the environment by establishing standards that transporters must adhere to when dealing with potentially dangerous materials. The regulations are meticulously designed to mitigate risks associated with hazardous materials during transport, ensuring that carriers, handlers, and recipients are all informed and properly equipped to manage these materials safely.
