How does PowerShell find help content when you run Get-Help?

When you run Get-Help for a cmdlet, where does PowerShell look for the help content? Choose the best explanation.

A PowerShell only uses local help files stored on the computer and never connects to the internet.

B PowerShell downloads help content every time you run Get-Help, ignoring local files.

C PowerShell first looks for updated help files on the internet, then falls back to local help files if no internet is available.

D PowerShell uses a cached version of help content stored in memory from the last session.

💡 Hint

Think about how Update-Help and Get-Help work together.

Get-Help first shows local help content. If updated help is available online and you run Update-Help, it downloads and stores new help files locally for future use.
