Household bleaches and disinfectants often contain solutions with chlorate(I) ions. When these solutions are heated, they decompose as shown: $3\text{ClO}^- \rightarrow \text{ClO}_3^- + 2\text{Cl}^-$. Which oxidation state is shown by chlorine in each of these three ions?
- A$+1, +3, -1$
- B$-1, +3, +1$
- C$+1, +5, -1$
- D$-1, +5, +1$
