Cuprite is a mineral that consists of copper(I) oxide \left(\mathrm{Cu}_2 \mathrm{O}\right). In cuprite, the oxidation state of the copper ion (\mathrm{Cu})  is +1 . Therefore, the correct oxidation state of the metal in cuprite is I.

Tenorite, on the other hand, is a mineral that consists of copper(II) oxide (CuO). In tenorite, the oxidation state of the copper ion (\mathrm{Cu}) is +2 . Therefore, the correct oxidation state of the metal in tenorite is II.
