Is Oracle Solaris officially declared UNIX?
I want to know all the official UNIX presently available in the market (whether free or paid).
Please correct me if I am wrong:
To the best of my knowledge, an operating system must satisfy all the terms and conditions as laid by the owners of "UNIX", The Open Group, to be coined as UNIX.
Linux is an UNIX-like kernel almost resembling UNIX but still open-source and free to distribute.

You can find that information on The Open Group's website, namely in the Register of Certified Products page.
Yes, Oracle Solaris is listed there.
