__________ is an open source version of Unix.

__________ is an open source version of Unix.

• A. Windows XP
• B. Mac OS X
• C. Linux
• D. Linus

Answer: (C)

Open-source means the code is freely available for anyone to view, modify, and share. Linux fits as the open-source version of Unix because it’s a free, community-developed operating system built from a Unix-inspired design and released under the GPL. It provides a Unix-like environment with a similar command-line interface, tools, and POSIX compatibility, and it runs on a wide range of hardware. Linux began as a personal project by Linus Torvalds in 1991 and has since grown into a family of distributions. In contrast, Windows XP is proprietary and not Unix-like, Mac OS X is Unix-based but not open source as a whole, and Linus is the developer’s name, not an operating system.
