Harmony Endpoint provides Endpoint Security Client packages forWindows, macOS, and Linux operating systems. This is explicitly documented in theCP_R81.20_Harmony_Endpoint_Server_AdminGuide.pdf. Onpage 19, under the section "Endpoint Security Client," it states: "The Endpoint Security client is available on Windows and Mac." This confirms support for Windows and macOS. Further clarification is provided onpage 51, under "Supported Operating Systems for the Endpoint Client," which lists "macOS" and "Linux" as supported platforms, alongside detailed support for Microsoft Windows onpage 49. Together, these references confirm that the client packages are offered for Windows, macOS, and Linux.

Option A ("Unix, WinLinux and macOS")is incorrect because "WinLinux" is not a recognized operating system, and Unix is not listed as a supported client OS in the documentation.

Option C ("macOS, iPadOS and Windows")is incorrect as iPadOS, an OS for mobile devices, is not mentioned as a supported platform for the Endpoint Security Client.

Option D ("Windows, AppleOS and Unix operating systems")is incorrect because "AppleOS" is not a standard term (the correct term is macOS), and Unix is not supported as a client OS.

Thus,Option Bis the only fully accurate choice based on the official documentation.
