Multiple Choice

Which of the following is not a Unix-like operating system?

Unix-like systems are those that resemble Unix in structure and behavior and typically provide a POSIX-compatible interface. Mac OS, Linux, and Unix all fit this description because they share a Unix heritage, use similar file permissions and process models, and offer standard utilities and shells aligned with POSIX. Windows OS, on the other hand, uses a different kernel (Win32/NT) and a distinct set of APIs and filesystem concepts. It isn’t POSIX-based by default, so it’s not considered Unix-like. (There are compatibility layers like WSL that let you run Linux tools, but that doesn’t change Windows’ own architecture.)
