Q. In which year was the Nuclear Suppliers Group (NSG) established?
Answer: 1974
Notes: The Nuclear Suppliers Group (NSG) was established in 1974 as a response to India's nuclear test that year. It aims to prevent nuclear proliferation by controlling the export of nuclear materials and technology. The NSG consists of 48 member countries, all of which are signatories to the Nuclear Non-Proliferation Treaty (NPT), except for India, Israel, Pakistan, and South Sudan, which are not NPT signatories.
