Aviation and Airport Security Practice Test.

The correct answer is A International Convention for the Physical Protection of Nuclear Material 1980. This treaty specifically addresses the safe and secure transportation of nuclear material, including the minimal limits for physical protection during international transport. Option B, the International Convention for the Suppression of Acts of Nuclear Terrorism 2005, focuses on the prevention and punishment of unlawful acts involving nuclear material, not the transportation itself. Option C, the Nuclear Non-Proliferation Treaty, deals with preventing the spread of nuclear weapons and technology. Option D, the Treaty on the Prohibition of Nuclear Weapons, prohibits the use, possession, and development of nuclear weapons, but does not address transportation. Essentially, only option A directly addresses the question and the other options are not as specific or relevant to the topic.
