A company needs to set up a petabyte-scale data warehouse in the AWS (CLF-C02)

Correct answer: C. Amazon Redshift.
Amazon Redshift is a fully managed data warehouse service that can handle petabyte-scale data. It is designed to store and analyze large amounts of data, making it an ideal choice for a petabyte-scale data warehouse.

Amazon DynamoDB (A) is a NoSQL database service that is optimized for fast, consistent performance, but it is not designed for large-scale data warehousing. Amazon RDS (B) is a relational database service that can handle large amounts of data, but it is not optimized for data warehousing at the petabyte scale. Amazon ElastiCache (D) is an in-memory caching service that can improve the performance of database queries, but it is not a data warehouse service.
