The correct answer focuses on the specific types of hazardous materials that are allowed on a plane. Certain hazardous materials, often referred to as hazmat, can be transported on planes under strict regulations and conditions set by organizations such as the Federal Aviation Administration (FAA) and the International Air Transport Association (IATA).

These regulations categorize various substances based on their risk, allowing only those that can be safely handled and transported under specific conditions. For example, medical supplies containing small quantities of hazardous materials may be permitted, provided they meet the regulatory guidelines.

The answer acknowledges that while some hazardous materials are indeed restricted due to safety concerns, there are designated types of hazmat that are allowed for transport, emphasizing the importance of compliance with transportation safety protocols. This distinction is crucial for ensuring both passenger safety and adherence to aviation regulations.
