Consider the following countries :
1. China
2. France
3. India
4. Israel
5. Pakistan
Which among the above are Nuclear Weapons States as recognized by the Treaty on the Non-Proliferation of Nuclear Weapons, commonly known as Nuclear Non-Proliferation Treaty (NPT)?

Correct Option: 1 and 2 only

The Treaty on the Non-Proliferation of Nuclear Weapons (NPT) recognizes only those states that manufactured and exploded a nuclear weapon or other nuclear explosive device prior to January 1, 1967, as Nuclear Weapon States. These are the five permanent members of the UN Security Council: the US, Russia, the UK, France, and China; India, Israel, and Pakistan are not signatories and thus not recognized as such under the treaty.
