Which of the following is a threat to Global security?

Terrorism

The correct answer is Option (3) → Terrorism

Non-traditional views of security have been called ‘human security’ or ‘global security’. Non-traditional notions of security go beyond military threats to include a wide range of threats and dangers affecting the conditions of human existence

The idea of global security emerged in the 1990s in response to the global nature of threats such as global warming, international terrorism, and health epidemics like AIDS and bird flu and so on. No country can resolve these problem alone. And, in some situations, one country may have to disproportionately bear the brunt of a global problem such as environmental degradation.
