Consider the following statements:1.The Nuclear Security Summits are periodically held under the aegis of the United Nations.2.The International Panel on Fissile Materials is an organ of International Atomic Energy Agency.Which of the statements given above is/are correct?

1. A

   1 only

   (a) 1 only. Nuclear Security Summits were US-initiated leaders’ summits (2010–2016), not a standing UN series. Statement 1 is false.

2. B

   2 only

   (b) 2 only. The International Panel on Fissile Materials is an independent expert group, not an IAEA organ. Statement 2 is false.

3. C

   Both 1 and 2

   (c) Both 1 and 2. Both institutional claims fail.

4. D

   Neither 1 nor 2

   (d) Neither 1 nor 2. NSS was a US-led process outside a UN periodicity mandate; IPFM is not an IAEA body. This is the official key.

Summary. Official key is (d) neither 1 nor 2. Nuclear Security Summits began in Washington in 2010 at President Obama’s call and were hosted by individual States, not as a UN organ’s calendar. The International Panel on Fissile Materials is a Princeton-based independent panel tracking highly enriched uranium and plutonium. IAEA runs safeguards and nuclear security guidance, but IPFM is not its organ. Both statements fall.
