  B. Amazon Athena Amazon Athena is a serverless query service that allows you to analyze data directly in Amazon S3 using standard SQL queries. You don't need to set up or manage any infrastructure; you only pay for the queries you run. It is well-suited for ad-hoc and exploratory analysis on data stored in S3 without the need for maintaining a separate database. Option A (Amazon Redshift) is a fully-managed data warehouse service and is more suitable for complex analytics and large-scale data warehousing scenarios. It might be more cost-effective for frequent and complex analytical workloads. Option C (Amazon Kinesis) is a service for real-time processing of streaming data and is not designed for running ad-hoc queries on stored data. Option D (Amazon RDS) is a managed relational database service and is not the most cost-effective choice for running queries directly on data stored in S3.

  A. Amazon Redshift: Suited for running complex queries on large datasets in a data warehouse. It involves provisioning and managing a cluster, and it may be more suitable for regular or ongoing analytics workloads.

  B. Amazon Athena: A serverless query service that allows you to analyze data in Amazon S3 using standard SQL without the need to manage infrastructure. It is cost-effective for occasional or ad-hoc queries, as you only pay for the queries you run.

  C. Amazon Kinesis: Primarily used for real-time data streaming and analytics. It is not designed for running ad-hoc queries on stored data.

  D. Amazon RDS: A managed relational database service. While it supports querying data, it is not typically used for ad-hoc analysis on large datasets stored in Amazon S3.

  In the context of occasional query analysis on data stored in Amazon S3, Amazon Athena (Option B) is the most cost-effective choice due to its serverless and pay-as-you-go nature.
