Why C is the best: Amazon Athena: Serverless SQL engine that queries data directly from S3, great for unstructured data (e.g., CSV, JSON, Parquet). Works seamlessly with AWS Glue Data Catalog, which helps define schema and manage metadata. No need to load data into a separate DB, saving time and cost. S3 Lifecycle + Glacier Deep Archive: Data older than 1 year is rarely accessed → S3 Glacier Deep Archive is the cheapest option for long-term storage. Data is retained indefinitely at very low cost. This combo meets both the analytics need and long-term cost optimization.
B, C seem both acceptable. The reason C is selected is because redshift spectrum need Glue Data Catalog as well which is not mentioned there.
