Answer: Amazon Redshift

The correct answer is D, Amazon Redshift. Amazon Redshift is a fully managed, petabyte-scale data warehouse service in the cloud. It is designed for large-scale data set analysis and is optimized for online analytical processing (OLAP) queries. Redshift allows for fast query performance and is capable of handling complex analytical queries, making it ideal for use with analytics dashboards. The other options are not primarily designed for data warehousing: Amazon ElastiCache is for in-memory caching, Amazon Aurora is a relational database, and Amazon RDS is a more general-purpose relational database service.
