The correct answer is option 3: OPEC. OPEC stands for the Organization of the Petroleum Exporting Countries, and it is an intergovernmental organization made up of oil-producing countries. India is not a member of OPEC, which means it is not part of this particular organization.
Option 1: Commonwealth of Independent States (CIS) is a political and economic organization formed by former Soviet Union countries. India is also not a member of the CIS.
Option 2: The South Asian Association for Regional Cooperation (SAARC) is an organization that promotes regional cooperation and integration among South Asian countries. India is indeed a member of SAARC.
Option 4: The World Trade Organization (WTO) is an international organization that deals with global trade regulations and disputes. India is a member of WTO.
In summary, while India is a member of SAARC and WTO, it is not a member of OPEC or the Commonwealth of Independent States.
