Which operating system is a clone of Unix?

• A. Windows
• B. Android
• C. Linux
• D. DOS

Answer: (C)

Linux is a Unix-like operating system, designed to resemble Unix in its structure and behavior. It follows Unix conventions such as a hierarchical file system, process management, permissions, and a large set of command-line tools, with compatibility to POSIX standards. Even though Linux was written from scratch, its developers modeled it after Unix principles, which is why it’s described as a Unix-like clone. Windows and DOS do not share Unix heritage, and Android, while built on the Linux kernel, isn’t itself a Unix clone but a Linux-based platform with its own user space. So Linux is the best fit as the Unix-like clone in this context.
