Which is not a member of what is referred to as the "World Bank Group"?

The World Bank Group includes the International Finance Corporation (IFC), the International Centre for Settlement of Investment Disputes (ICSID), and the Multilateral Investment Guarantee Agency (MIGA). The Economic and Social Council (ECOSOC) is a principal organ of the United Nations, not a member of the World Bank Group, so the answer is the Economic and Social Council.
