1. Identify the oxidation states of the elements in the reactants and products.

- Mn in MnO_2: +4

- Mn in MnCl_2: +2

- Cl in HCl: -1

- Cl in Cl_2: 0

2. Determine which element increases in oxidation state (oxidizes).

- Mn changes from +4 to +2 (reduces).

- Cl changes from -1 to 0 (oxidizes).

3. The species that oxidizes is Cl (Chlorine).

Answer: c) Cl
