The correct answer is: B. Nuclear Non-proliferation Treaty (NPT)
The Nuclear Non-proliferation Treaty (NPT) is an international treaty aimed at preventing the spread of nuclear weapons and weapons technology. It was opened for signature in 1968 and entered into force in 1970. The NPT has three main pillars: non-proliferation, disarmament, and the peaceful uses of nuclear energy.
The NPT prohibits the transfer of nuclear weapons or nuclear weapons technology to non-nuclear-weapon states. It also prohibits non-nuclear-weapon states from acquiring nuclear weapons or nuclear weapons technology. The NPT does allow non-nuclear-weapon states to develop nuclear energy for peaceful purposes, but only under strict safeguards to ensure that the nuclear material is not used for weapons purposes.
