The Inca's mit'a system referred to:

• A. A tax paid in coin to the state.
• B. A military draft for officers.
• C. A labor draft where communities contributed workers for state projects.
• D. An educational program for scribes.

Answer: (C)

The mit’a was a labor obligation in the Inca state: communities contributed workers for public works and state projects, rather than paying taxes in money. This system organized work through local groups (ayllu) in rotating service periods, supplying labor for building roads and bridges, maintaining agricultural terraces, constructing temples, mining, and other state needs. By mobilizing large teams of workers, the empire could sustain infrastructure and projects essential to governance and agriculture. It isn’t a monetary tax, a military draft for officers, or an educational program for scribes, which is why the labor-draft interpretation best fits what mit’a referred to.
