The correct option is The entire prompt plus nearby code and information about the project directory can be shared.

This is correct because Copilot Chat in JetBrains IDEs can use your full prompt together with surrounding code and additional project context to generate a response. The service can consider code near the cursor and details from the project such as file names and paths, which gives it a broader understanding of your workspace than a typical inline completion request.

Only the currently open file is provided is incorrect because chat can draw on more than a single file and can include nearby code and project information.

Only the prior chat messages are considered is incorrect because chat also uses code context from the IDE and information about your project, not just the conversation history.

No contextual data is included for chat is incorrect because chat relies on the prompt along with relevant code and workspace context to produce useful answers.
