The best choice would be A because a Sub procedure is being created and it requires a header that starts with `Private Sub`. The header should also include the parameter list, which in this case has two parameters - `strItem` and `decPrice`. Both these parameters are being passed as values (`ByVal`), which means they can be used within the procedure but any changes made to them will not be reflected outside the procedure.
