Answer questions from the passage below:

Arms control regulates the acquisition or development of weapons. The Anti-ballistic Missile (ABM) Treaty in 1972 tried to stop the United States and Soviet Union from using ballistic missiles as a defensive shield to launch a nuclear attack. While it did allow both countries to deploy a very limited number of defensive systems, it stopped them from large-scale production of those systems. 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.

In which year was the Anti-ballistic Missile (ABM) Treaty signed?

1972

The correct answer is Option (2) → 1972

The passage clearly states that the Anti-ballistic Missile (ABM) Treaty was signed in 1972 between the United States and the Soviet Union.
