Which one of the following international organisations came into bein…

The correct answer is Option (4) → International Atomic Energy Agency

Option (1) Nuclear Suppliers Group — Incorrect. It is a group of countries that supply nuclear material and technology and agree on common rules for its export, so that it is not used to make weapons. It was not set up to carry out the “Atoms for Peace” proposal.

Option (2) North Atlantic Treaty Organization — Incorrect. NATO is the Western alliance that the Baltic and east European states wanted to join after the end of the Soviet bloc; it has nothing to do with the peaceful use of nuclear energy.

Option (3) International Telecommunication Union — Incorrect. It is one of the specialised agencies of the UN; its field is telecommunications, so it has no role in promoting the peaceful use of nuclear energy, which is what “Atoms for Peace” was about.

Option (4) International Atomic Energy Agency — Correct. The International Atomic Energy Agency (IAEA), established in 1957, came into being to implement US President Dwight Eisenhower’s ‘Atoms for Peace’ proposal.
