Tndia is not a member of which one of the following?

India is not a member of the Commonwealth of Independent States (CIS). The CIS is a regional intergovernmental organization formed following the dissolution of the Soviet Union, primarily comprising former Soviet Republics [t2]. In contrast, India is a founding member of the World Trade Organization (WTO), which was established to regulate global trade [c1][c5]. India is also a key member of the South Asian Association for Regional Cooperation (SAARC), established in 1985 alongside neighbors like Bangladesh, Bhutan, and Pakistan to foster regional cooperation [c3][c4]. Regarding OPEC, while India is a major consumer and maintains high-level dialogues with the organization, it is not a member; OPEC consists of 13 oil-exporting nations such as Saudi Arabia and Venezuela [c2]. However, in the context of this specific question, the CIS is the most distinct entity where India lacks any formal membership or consumer-dialogue status comparable to its international trade and regional roles.
