D is correct here. Event Time field needs an immutable field and Last Modified Data will keep changing.

The Event Time field is a special field type that captures the timestamp of an event in a data stream. It is used to track the chronological order of events and to enable time-based segmentation and activation. When ingesting Case data, the recommended field to be associated with the Event Time field is the Last Modified Date field. This field reflects the most recent update to the case and can be used to measure the case duration, resolution time, and customer satisfaction. The other fields, such as Resolution Date, Escalation Date, or Creation Date, are not as suitable for the Event Time field, as they may not capture the latest status of the case or may not be applicable for all cases.

When ingesting Case data into Data Cloud, the field recommended to be associated with the Event Time field is: D. Creation Date The Creation Date typically represents the initial point in time when the case was logged, making it a reliable reference for the Event Time field. This ensures that the event timeline accurately reflects when the case was first created.

Event Time is the Primary Key. All the other fields will generate duplicates every time their values have been changed. https://help.salesforce.com/s/articleView?id=sf.c360_a_container_basics_attributes.htm&type=5
