A penetration tester is writing a Bash script to enumerate DNS records for a domain. The script needs to perform a zone transfer attempt and, if it fails, fall back to a dictionary-based subdomain brute force. Which Bash construct should the tester use to handle the conditional logic?

A `case` statement that matches the output of the `dig` command.

A `while` loop that runs `dig` until it succeeds.

An `if` statement that checks the exit status of the `dig axfr` command and runs the brute force in the `else` block.

A `for` loop that iterates over the output of `dig`.
