Amazon CloudWatch is the correct selection because it is specifically designed to provide monitoring and observability for AWS resources and applications. It collects and tracks metrics, collects log files, and sets alarms, enabling users to react to changes in their environment in real-time. This service allows users to understand the performance of their resources, optimize resource utilization, and gain insights into their applications.

For instance, you can create custom dashboards in CloudWatch to visualize your operational data alongside AWS resource metrics, which helps in identifying trends and issues quickly. Additionally, CloudWatch Events can respond to system events and initiate actions based on predefined rules, enhancing automation and responsiveness in your AWS environment.

Other options, while important in their respective functions, do not provide the same level of insight and monitoring capabilities. The AWS Pricing Calculator is a tool for estimating costs of AWS services. Amazon DynamoDB is a fully managed NoSQL database service, focusing on data storage rather than monitoring. Amazon EKS (Elastic Kubernetes Service) is used for deploying and managing containerized applications with Kubernetes, but it does not primarily serve as a monitoring and insights tool. Hence, CloudWatch stands out as the dedicated service for acquiring insights and monitoring capabilities across AWS resources and applications.
