A Mule implementation uses a HTTP Request within an Unit Successful scope to connect to an API.
How should a permanent error response like HTTP:UNAUTHORIZED be handle inside Until Successful to reduce latency?

• A.Configure retrying until a MULERETRY_EXHAUSTED error is raised or the API responds back with a successful response.
• B.In Until Successful configuration, set the retry count to 1 for error type HTTP: UNAUTHORIZED.
• C.Put the HTTP Request inside a try scope in Unit Successful.
  In the error handler, use On Error Continue to catch permanent errors like HTTP UNAUTHORIZED.
• D.Put the HTTP Request inside a try scope in Unit Successful.
  In the error handler, use On Error Propagate to catch permanent errors like HTTP UNAUTHORIZED.
