Substances A, B, and C can all act as oxidizing agents. In solution, A is green, B is yellow, and C is red. In the reactions in which they participate, they are reduced to A−, B−, and C− ions, all of which are colorless. When a solution of C is mixed with one containing B− ions, the color changes from red to yellow.

Which species is oxidized?
