C; Glue can use FindMatches transformation to find duplicates

It is C as described in the tutorial - https://docs.aws.amazon.com/glue/latest/dg/machine-learning-transform-tutorial.html LakeFormation can also invoke a FindMatches algorithm (because it manages Data Ingestion through Glue), but we don't have a data lake in this example. No one would build a whole Data Lake - a process that takes days - only to find some matching records.

Option C

Lake Formation helps clean and prepare your data for analysis by providing a Machine Learning (ML) Transform called FindMatches for deduplication and finding matching records. For example, use FindMatches to find duplicate records in your database of restaurants, such as when one record lists “Joe's Pizza” at “121 Main St.” and another shows “Joseph's Pizzeria” at “121 Main.” You don't need to know anything about ML to do this. FindMatches will simply ask you to label sets of records as either “matching” or “not matching.” The system will then learn your criteria for calling a pair of records a match and will build an ML Transform that you can use to find duplicate records within a database or matching records across two databases. https://aws.amazon.com/lake-formation/features/

AWS Lake Formation FindMatches is a new machine learning (ML) transform that enables you to match records across different datasets as well as identify and remove duplicate records, with little to no human intervention Ans is D
