Answer: Cloud Composer
The correct answer is D: Cloud Composer. Cloud Composer is a fully managed workflow orchestration service based on Apache Airflow. It allows you to define, schedule, and manage complex workflows with multiple steps, including shell scripts, Hadoop jobs, and BigQuery queries. It also supports dependency management and provides built-in retry mechanisms for failed steps, making it a suitable choice for managing interdependent batch jobs that require specific execution order and retries.
