There are too many cooks in this particular kitchen, but checking a
couple of places should be enough in most cases: org-file-apps is the
most immediate place but unless you've customized it, it should say

       ...
       ("\\.pdf\\'" . default)
       ...

which takes us to the next cook: mailcap. ~/.mailcap overrides the
system /etc/mailcap and there may be more (`man 5 mailcap' should reveal
the rest), so check them in order. I prefer xpdf so my mailcap says:

,----
| $ grep pdf ~/.mailcap
| application/pdf; xpdf -q %s
`----

I like putting things in ~/.mailcap, but you can season to taste.

HTH,
