Nope -- it is in lib/dns/rootns.c in the source code tree….

When BIND is compiled into a binary this gets baked in….

You can verify this by running strings on the binary. E.g:

wkumari$:~$ strings /usr/local/sbin/named | grep A.ROOT-SERVERS.NET
.                       518400  IN      NS      A.ROOT-SERVERS.NET.
A.ROOT-SERVERS.NET.     3600000 IN      A       198.41.0.4
A.ROOT-SERVERS.NET.     3600000 IN      AAAA    2001:503:BA3E::2:30
