The correct statement is GitHub Copilot requires a GitHub account and is only available to signed in GitHub users.

This is correct because Copilot authenticates through a GitHub identity in every supported environment. You must use a GitHub account and have a trial or subscription in order to enable and use Copilot in Visual Studio Code, Microsoft Visual Studio, and other supported editors. The licensing and sign in flow are handled by GitHub rather than by other identity systems.

Non GitHub users can sign up with any email directly in Visual Studio to activate GitHub Copilot is incorrect because Visual Studio prompts you to sign in with GitHub to authorize and enable Copilot and an email alone cannot activate the service.

Non GitHub users can use GitHub Copilot from Visual Studio Code or Microsoft Visual Studio if they have an Azure subscription is wrong because an Azure subscription does not grant access to Copilot. Copilot access is tied to a GitHub account and its subscription.

Non GitHub users can turn on GitHub Copilot from Google Cloud Shell Editor without linking a GitHub identity is false because even in VS Code compatible environments the Copilot extension requires you to sign in with a GitHub account.
