Comprehensive and Detailed Explanation:
The correct answer is C - Data Extract with the Tracking Extract type > File Transfer from Safehouse > File Transfer unzip > Import File.
* Tracking Extract Activity pulls detailed email event data, including 'Not Sent' events, into a compressed file (.zip).
* You need a File Transfer Activity to move the file from the Safehouse and unzip it.
* After unzipping, Import Activity loads the extracted data into a Data Extension where queries can run.
# Why others are wrong:
* A and B: Data Extension Extract type is for DE records, not tracking events like Not Sent.
* D: Data Factory Utility is not part of the standard Automation Studio activities for these operations.

Salesforce Help - Tracking Extract and Automation Studio:
"Use Tracking Extract to retrieve event-level data, including Not Sent events, then use a File Transfer Activity to unzip and import the extracted data for analysis or reporting." (Source: https://help.salesforce.com/s/articleView?id=sf.mc_as_tracking_extract_activity.htm)
