A Correct answer
Explanation

NUL is a reserved device name in Windows and cannot be used for files or folders. Other reserved names include CON, PRN, AUX, and COM1-9. These names date back to MS-DOS and are reserved for backward compatibility with legacy device drivers. CON1 and AUX1 work fine because they're not exact matches to the reserved names.
