Answer:
The correct answer is A. A reason to institute sanctions against another country would be Iran's attempts to develop nuclear weapons.
Step-by-step explanation:
Since the formation of the UN in 1945 and, especially, since the signing of the Nuclear Non-Proliferation Treaty in 1968, the vast majority of the world's nations have agreed not to develop nuclear energy for military purposes (that is, not to develop bombs). nuclear weapons), using said technology solely for peaceful purposes. Thus, only the member countries of the UN Security Council (USA, China, France, Russia and Great Britain) are authorized to possess and develop this type of weaponry, which is strictly prohibited for the remaining countries, as in the case of Iran.
Therefore, if Iran tries to develop this type of nuclear weapons, it would be subject to international sanctions for violating this international treaty.
