The correct option is An AI-powered assistant that suggests code inside supported editors. When enabled in VS Code or JetBrains IDEs, Copilot integrates into the editor to offer inline, context aware code suggestions that you can accept, modify, or ignore as you work.

Copilot analyzes the surrounding code and your comments to propose lines, entire functions, and tests, which helps speed up common patterns and boilerplate. It works within the editor experience so suggestions appear as you type and fit naturally into your existing workflow.

A built-in tool for creating and managing Git branches is incorrect because branching is handled by Git and the IDE version control features. Copilot does not create or manage branches.

Cloud Code is incorrect because that is a different plugin focused on cloud development tasks and it does not describe what Copilot does inside editors.

A command-line utility for automating GitHub workflows is incorrect because Copilot is not a CLI tool. Workflow automation on the command line is handled by other tools while Copilot operates inside the editor.
