Which group was formed in 1980 to represent all Aboriginal peoples across Canada in their dealings with the federal government?

• A. Self-determination
• B. Land claims
• C. Assembly of First Nations
• D. Quebecois

Answer: (C)

The main idea here is identifying who acts as the national voice for First Nations in dealings with the federal government. The Assembly of First Nations fits that role: it is the national umbrella organization that represents First Nations across Canada in Ottawa, coordinating policy, advocacy, and negotiations on issues like treaties, funding, and governance. The other options describe either a concept (self-determination), a specific policy area (land claims), or a distinct non-Aboriginal group (Quebecois), none of which names a national Indigenous representative body.
