The value of the argument is stored in the `options[:who]` hash.\\n4. **Gets the name to greet:**\\n   - `who = options[:who] || \"world\"` retrieves the value of the `:who` option from the `options` hash. If the option is not provided, it defaults to \"world\".\\n5. **Prints the greeting:**\\n   - `puts \"Hello, \#{who}!\"` prints the greeting message with the name of the person being greeted.
