Out of the following, which international organisation is not a U.N. agency concerned with Human Rights ?

The World Trade Organization (W.T.O.) is an international trade organisation outside the United Nations specialised-agency system whose primary mandate is regulating multilateral trade rules rather than human rights. By contrast, the International Labour Organization (I.L.O.), the World Health Organization (W.H.O.), and UNICEF are UN bodies with direct mandates covering labour rights, the right to health, and children's rights.
