The error message "uri keypath not found" suggests that the URI used to fetch the BGP configuration is incorrect. This means the BGP data resource identifier in the URL is incorrect, making option A the correct answer. The script is attempting to access a RESTCONF resource that does not exist on the server, hence the "404 Not Found" error.
