You need to identify the duplicate pet records, so they can be manually merged by...

To identify duplicate records, you need to configure both duplicate detection rules and duplicate detection jobs.

Since Terra Flora requires identifying duplicate pet records across various fields, creating three duplicate detection rules is likely necessary to cover different columns (such as name, breed, and dietary requirements) in the Pet table.

One duplicate detection job is sufficient to run these rules concurrently, scanning the database for duplicates across the specified columns. This job can be scheduled or run manually.

Option B is correct as it ensures comprehensive coverage with three rules addressing various fields and one job to manage the duplicate detection process.
