"The world council of Indigenous people" was formed in which year?

1975

The correct answer is Option (3) - 1975

Issues related to the rights of the indigenous communities have been neglected in domestic and international politics for very long. During the 1970s, growing international contacts among indigenous leaders from around the world aroused a sense of common concern and shared experiences. The World Council of Indigenous Peoples was formed in 1975. The Council became subsequently the first of 11 indigenous NGOs to receive consultative status in the UN.
