A team wants every Copilot-generated pull request to produce a drift report. The workflow should run on pull requests to main, read repository contents, run a script that compares the PR files against the issue scope, and persist the report as a workflow artifact for reviewers. Which option completes the workflow?

The correct option is pullrequest for Missing value 1 because the requirement specifies the workflow should run on pull requests. read for Missing value 2 is correct because the workflow only needs to read repository contents and pull request information, not modify them. actions/upload-artifact@v4 for Missing value 3 is the correct action to persist the generated report as a workflow artifact, making it available for download by reviewers. Incorrect options: push would trigger on every push, not specifically pull requests. write permissions are unnecessary. actions/cache@v4 is for caching files between workflow runs, not for persisting artifacts for review. workflowdispatch requires manual triggering. actions/download-artifact@v4 is for downloading artifacts, not uploading them. schedule triggers at scheduled times, not on pull requests. none permissions would prevent reading repository contents. actions/upload-pages-artifact@v3 is for GitHub Pages deployments, not general artifact storage.
