A Correct answer
Explanation

Without using the shift command, shell scripts can directly reference only $0 through $9. The \$0 variable holds the script name, while \$1-\$9 hold the first nine positional parameters. Beyond \$9, you must use shift or ${n} syntax to access higher-numbered arguments.
