A Correct answer
Explanation

The /etc/shells file contains the list of valid login shells on Unix/Linux systems. The cat command displays file contents, so cat /etc/shells shows all available shells. The /tmp and /root directories are not standard locations for shell configurations, and $SHELLS is not a standard environment variable.
