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.

Which among the following statement is correct about NPT?

The NPT did not abolish nuclear weapons.

The correct answer is Option (3) → The NPT did not abolish nuclear weapons.

The passage explicitly states, "The NPT did not abolish nuclear weapons; rather, it limited the number of countries that could have them."
