You are pen testing a Windows system remotely via a raw netcat shell. You want to quickly change directories to where the Windows operating system resides, what command could you use?

'cd systemroot' treats 'systemroot' as a literal folder name and will fail with a path error because no directory named exactly 'systemroot' exists by default.

Note: 'cd-' is not a valid Windows CMD command for navigating to the operating system directory - the technically correct Windows command is 'cd %systemroot%' (option D), which uses environment variable expansion to resolve to C:\Windows. This answer key appears to contain an error; option D is the accurate answer.

'/systemroot/' uses Unix-style forward-slash notation which does not trigger Windows environment variable expansion and is not a valid Windows path.

'cd %systemroot%' is actually the correct Windows command that expands the built-in environment variable to C:\Windows - making this the technically accurate answer despite the provided answer key.
