A Process Is Fed Cases to Work from a Spreadsheet

A Process is fed cases to work from a spreadsheet held in a shared drive. The location of the shared drive is different between Development and Production environments. How should this be managed?

A) During the build and test phase, hold the 'Development' path to the spreadsheet in a data item within a Process. When the Process is imported into Production it will be opened and the data item will be amended to hold the 'Production' path.
B) During the build and test phase, hold the 'Development' path to the spreadsheet in a data item within a Process. Expose this data item as a Session Variable. When the Process is run in Production, this Session Variable value can be set in Control Room
C) Hold the Path to the spreadsheet as an Environment Variable
D) Pass the Path as a Startup Parameter when the process starts
