Which of the following scripting languages is the most commonly used for system administration on Windows operating systems?

PowerShell is the most commonly used and powerful scripting language for system administration on Windows operating systems, providing comprehensive access to the .NET framework, COM objects, and WMI for extensive automation capabilities. It is deeply integrated into Windows Server and client OS management.

Python is a versatile general-purpose scripting language, but it is not natively integrated or as predominantly used for Windows-specific system administration as PowerShell.

Bash is a Unix shell and command language primarily used on Linux and macOS, not for native Windows system administration.

JavaScript is primarily a client-side scripting language for web browsers and server-side with Node.js, not a core language for Windows system administration.
