Which AWS service can the company use to meet these requirements?

Explanations:

AWS Trusted Advisor is a service that provides real-time guidance to help provision your resources following AWS best practices. However, it does not centralize operational data or automate tasks across EC2 instances.

AWS Systems Manager is a management service that provides operational data from multiple AWS services and allows automation of tasks across EC2 instances, making it the best fit for centralizing operational data and automating management tasks.

AWS CodeDeploy is a service for automating the deployment of applications to EC2 instances, but it does not provide functionality for centralizing operational data or automating general tasks across instances.

AWS Elastic Beanstalk is a platform as a service (PaaS) that allows users to deploy and manage applications. It abstracts the underlying infrastructure but does not specifically centralize operational data or automate tasks across EC2 instances.
