Which organization produced rules for transporting dangerous goods?

The International Air Transportation Association (IATA) is the correct answer because it plays a critical role in establishing guidelines for the safe and efficient transport of goods, particularly in the aviation sector. IATA is known for its Dangerous Goods Regulations (DGR), which provide detailed standards and procedures that airlines and shippers must follow to ensure that hazardous materials are transported safely and in compliance with international laws. This includes classification, packaging, labeling, and documentation requirements specifically tailored for air transport.

The other organizations mentioned have significant roles in their respective areas. For instance, the Federal Aviation Administration (FAA) regulates all aspects of civil aviation, but its focus is primarily on safety standards and regulations within the United States, rather than on the broad international standards for dangerous goods transport. The World Health Organization (WHO) is mainly concerned with public health and does not specifically address transport regulations for dangerous materials, while the International Maritime Organization (IMO) focuses on maritime transport safety but is not responsible for aviation transport. Hence, IATA is the key agency for rules related to transporting dangerous goods by air.
