Which operating system is recognized as an open-source version of UNIX?

• A. Windows
• B. Linux
• C. MacOS
• D. FreeBSD

Answer: (B)

The correct choice recognizes Linux as an open-source operating system that is derived from the principles of UNIX. Open-source means that the source code of the operating system is freely available for anyone to view, modify, and distribute. Linux was created by Linus Torvalds in 1991 as a free alternative to the UNIX operating system. It shares many of the same features and functionalities as UNIX but is developed under the GNU General Public License, fostering a strong community of developers and users who contribute to its continual improvement and adaptability. In contrast, Windows is a proprietary operating system developed by Microsoft and is not open-source. Similarly, MacOS is an operating system created by Apple and is also proprietary, built on a UNIX-like foundation, but it does not share the open-source nature of Linux. FreeBSD, while derived from the original UNIX, is a separate operating system that is also open-source but does not fall under the Linux umbrella. Therefore, Linux stands out as the prominent open-source candidate directly associated with UNIX-like systems.
