A proposed three-step mechanism for the coupled catalytic destruction of stratospheric ozone is represented below.

\[\text{Step 1: } \text{Br(g)} + \text{O}_3\text{(g)} \rightarrow \text{BrO(g)} + \text{O}_2\text{(g)}\]
\[\text{Step 2: } \text{Cl(g)} + \text{O}_3\text{(g)} \rightarrow \text{ClO(g)} + \text{O}_2\text{(g)}\]
\[\text{Step 3: } \text{BrO(g)} + \text{ClO(g)} \rightarrow \text{Br(g)} + \text{Cl(g)} + \text{O}_2\text{(g)}\]

Based on the proposed mechanism, which of the following correctly identifies the catalyst(s) and intermediate(s) in this reaction cycle?
