   • ARun all services in parallel using the task runner's parallel execution feature.
   • BUse a shell script that checks git diff and conditionally runs the build for each service.
   • CSplit the monorepo into multiple repositories, each with its own pipeline.

   A CI pipeline uses a task runner to build a mobile app. The build process includes code compilation, running unit tests, and packaging the app. The team wants to ensure that if a unit test fails, the packaging step is skipped to save time. What is the best way to configure the task runner?

   • AUse a separate pipeline for packaging and manually trigger it after tests pass.
   • BRun all steps in a single script and use conditional statements to check the test exit code.
   • CRun the packaging step before the tests to ensure the package is always available.
   • DDefine the steps as separate tasks and configure the packaging task to depend on the successful completion of the test task.
