Explanation:

❌ A. Tracking Extract
Tracking Extract alone is not a complete automation to move data to an SFTP location. While it is used to retrieve email send tracking data (like opens, clicks, bounces, etc.), it only creates a file in the Safehouse. The Safehouse is a temporary encrypted storage area within Marketing Cloud. You still need a File Transfer activity afterward to actually move that file to the SFTP location. Therefore, this option only represents half of the process and is insufficient by itself.

✅ B. Tracking Extract > File Transfer
This is a complete and correct automation setup. The Tracking Extract activity pulls tracking data (opens, clicks, etc.) and saves the file in the Safehouse. The File Transfer activity then moves that file from the Safehouse to the customer’s SFTP location. This approach ensures the automation exports the required data and delivers it to the external system without manual intervention. This combination is efficient and scalable for daily or weekly reporting on email performance.

✅ C. Query (Data Views) > Data Extension Extract > File Transfer
This is another correct and complete sequence. First, a Query Activity is used to retrieve tracking data from Data Views (system tables like _Open, _Click, etc.) and stores the result in a Data Extension. Next, a Data Extension Extract converts that data extension into a flat file in the Safehouse. Finally, a File Transfer activity moves the file from the Safehouse to the SFTP location. This setup is often used when you want to customize the data being extracted.

❌ D. Query (Data Views) > File Transfer
This setup is incomplete. A Query Activity retrieves and stores data into a Data Extension, but a File Transfer activity alone cannot extract data from that Data Extension directly. There is a missing step: you need a Data Extension Extract activity to create a downloadable file in the Safehouse before the File Transfer can move it to the SFTP. Without that, the File Transfer has nothing to move, and the automation will fail to achieve its goal.
