The correct answer is C. Windows Server 2022, because Windows Server editions are specifically designed to run server workloads, such as file services, Active Directory, DNS, DHCP, virtualization, and application hosting.

According to the Quentin Docter – CompTIA A+ Complete Study Guide, Windows Server operating systems differ significantly from desktop versions. They support server roles, higher hardware limits, and enterprise features not available in client editions.

The Travis Everett & Andrew Hutz – All-in-One Exam Guide explains that Windows 10 Enterprise and Windows 11 Pro are client operating systems intended for end-user workstations. While they can connect to servers, they are not designed to function as servers themselves.

The Mike Meyers / Mark Soper Lab Manual clarifies that version identifiers like 22H2 represent feature updates for Windows client operating systems, not standalone server products.

Because the question asks which version would most likely be installed on a server, the correct choice is Windows Server 2022, making C the correct answer.
