Who is not member of ‘SAARC’ in the following?

Singapore
India
Pakistan
Bhutan

The correct answer is (a) Singapore.

The South Asian Association for Regional Cooperation (SAARC) is an intergovernmental organization comprising eight member states in South Asia: Afghanistan, Bangladesh, Bhutan, India, Maldives, Nepal, Pakistan, and Sri Lanka.

Singapore is not a member of SAARC because it is not located in South Asia. It is a city-state in Southeast Asia.
