Final answer:
Option B, Sun Solaris is the correct answer that supports operating system virtualization; Windows NT and Windows XP do not support it natively.
Step-by-step explanation:
The student has asked about which of the following operating systems support operating system virtualization: (a) Windows NT, (b) Sun Solaris, (c) Windows XP, (d) Compliance. The correct answer is Sun Solaris, which is an operating system known to support virtualization technologies, especially with its later versions.
Windows NT and Windows XP are earlier versions of Windows operating systems which did not have built-in support for hardware virtualization, a feature that became common in later operating systems. The term 'Compliance' does not refer to an operating system, so it does not support operating system virtualization inherently.
Operating system virtualization is crucial in modern computing as it allows for the creation of multiple virtual machines (VMs), each with its own operating system instance, on a single physical server. This technology revolutionized the way computing resources are utilized and managed.
