Which of the following treaties aimed at limiting nuclear arms?

The Strategic Arms Limitations Treaty II (SALT II) and the Strategic Arms Reduction Treaty (START)

The correct answer is Option 4 - The Strategic Arms Limitations Treaty II (SALT II) and the Strategic Arms Reduction Treaty (START)

SALT II and START were both arms control treaties between the US and the Soviet Union focused on limiting the number of nuclear weapons.

The US and Soviet Union signed a number of other arms control treaties including the Strategic Arms Limitations Treaty II or SALT II and the Strategic Arms Reduction Treaty (START). The Nuclear Non-Proliferation Treaty (NPT) of 1968 was an arms control treaty in the sense that it regulated the acquisition of nuclear weapons: those countries that had tested and manufactured nuclear weapons before 1967 were allowed to keep their weapons; and those that had not done so were to give up the right to acquire them. The NPT did not abolish nuclear weapons; rather, it limited the number of countries that could have them.
