The correct option is Direct Copilot Chat inside GitHub.com for repos and pull requests.

Copilot Enterprise includes GitHub.com chat that brings chat and code awareness directly into repositories and pull requests on the web so teams can ask questions and get context from code and discussions without leaving GitHub. Business and Individual plans provide chat experiences in supported IDEs but they do not include GitHub.com chat, which makes this capability exclusive to the Enterprise plan.

The option Inline code completions in supported IDEs is available to all plans, including Individual, Business, and Enterprise, so it is not exclusive to Enterprise.

The option Copilot Chat in IDEs such as Visual Studio Code and JetBrains is offered across Individual, Business, and Enterprise plans, so it is not unique to Enterprise.

The option Organization wide IP indemnity for generated suggestions is provided to Copilot Business customers in addition to Enterprise, so it does not meet the requirement of being Enterprise only.
