DBI to use for Citizenship in validation and eligibility fast formulae.

Summary:

I want to validate against the value of citizenship as per the screen print, but I am uncertain of the correct DBI to use in this case.

Content (required):

I can see the below 2 DBI's and I think that the 1st one will return the citizenship value captured in the screen print, but I am unsure. I think the 2nd DBI will refer to e.g. UAE in this case as opposed to Emirati. Is there anyone who have used these DBI's before and is able to guide me please?
