The correct answer is D, Amazon Redshift. Amazon Redshift is a fully-managed data warehousing service that allows you to run complex queries on large datasets. It is optimized for online analytic processing (OLAP) workloads and is well-suited for business intelligence and operational analytics use cases. Amazon Redshift can directly query data stored in Amazon S3, making it an excellent choice for analyzing large amounts of data in a data lake. The other options are not suitable for this use case: Amazon RDS is a relational database service, Amazon Neptune is a graph database service, and Amazon DynamoDB is a NoSQL database service, none of which are designed for large-scale data warehousing and analytics like Amazon Redshift.
