A	LINUX
B	IRIX
C	Ubuntu
D	A/UX

Explanation:

Detailed explanation-1: -Hewlett-Packard Unix (HP-UX) is an implementation of the Unix operating system that is based on the UNIX System V, developed by Hewlett-Packard and first released in 1984. It was originally developed for HP’s proprietary Integral PC and then made to run on 9000 series business servers.

Detailed explanation-2: -Some past and present commercial versions include SunOS, Solaris, SCO Unix, AIX, HP/UX, and ULTRIX. Freely available versions include Linux, NetBSD, and FreeBSD (FreeBSD is based on 4.4BSD-Lite).

Detailed explanation-3: -Until recently, there were basically two main flavors of Unix: System V (five) from AT&T, and the Berkeley Software Distribution (BSD). SVR4 is essentially a merge of these two flavors. OSF/1 from the Open Software Foundation was released in 1991 (as a direct competitor to System V) and may change this picture.

Detailed explanation-4: -UNIX systems also have a graphical user interface (GUI) similar to Microsoft Windows which provides an easy to use environment.
