An automation script should ask Copilot CLI one question, capture its response, and finish rather than open a continuing interactive session. Which invocation matches that use?

1. git log --copilot "Summarize the recent changes in this repository"
2. copilot --version "Summarize the recent changes in this repository"
3. copilot --help "Summarize the recent changes in this repository"
4. copilot -p "Summarize the recent changes in this repository"
