While I agree 100% that technically D & E would do that, C and E would be correct. Since you dont know if you are using c# code or anything else that can actually trigger an upsert, the only way to guarantee no dups is C and E

Selected Answer: DE
Use the Upsert method - The Upsert method can be used to insert new records or update existing records based on the primary key of the record. This ensures that records are not duplicated in Dataverse. Use Alternate key - An alternate key is a unique identifier for a record that is defined by the user and can be used instead of the primary key to avoid duplicates. By defining an alternate key on the entity in Dataverse that will be used to store the data from the external data source, the integration can use the alternate key to check for existing records and avoid creating duplicates.

Should be AlternateKey and Upsert. An AlernateKey is aleady unique, so you don't need Duplicate Detection

I agree, it says each answer is part of the solution. Using Upsert + alternate keys is a good way to ensure there's no duplicates.
