A. B. C. D.Correct Answer - B.
AWS Trusted Advisor could be used to check usage details of AWS resources and whether your account approaches or exceeds the limit (also known as quotas) for AWS services and resources.
Option A is incorrect as Amazon CloudWatch is a tool that monitors application usage & provides operational health of resources, but does not provide service limit usage details of resources in AWS.
Option C is incorrect as AWS Systems Manager helps manage & control resources in the AWS cloud, but will not provide service limit usage details of resources in AWS.
Option D is incorrect as AWS Config is a tool to audit & evaluate the configuration of AWS resources.
But it will not provide service limit usage details of resources in AWS.

https://aws.amazon.com/premiumsupport/technology/trusted-advisor/faqsThe service that can be used to check if the number of EC2 instances approaches the limit is Amazon CloudWatch.
Amazon CloudWatch is a monitoring service provided by AWS that can monitor resources and applications running in AWS, such as Amazon EC2 instances, Amazon RDS databases, and Amazon S3 buckets. CloudWatch can collect and track metrics, collect and monitor log files, and set alarms.
CloudWatch can be used to monitor the number of EC2 instances launched in an AWS account. It can provide the necessary visibility to understand if the number of EC2 instances approaches the limit set for the account. The EC2 instances can be monitored using CloudWatch metrics like CPU utilization, network traffic, and disk usage.
AWS Trusted Advisor provides recommendations to help optimize AWS resources and services based on best practices in five categories, including cost optimization, security, fault tolerance, performance, and service limits. AWS Trusted Advisor can provide information on EC2 instance limits, but it is not a monitoring service.
AWS Systems Manager is a management service that helps to manage Amazon EC2 instances and on-premises instances. It provides a suite of tools for configuration management, automation, and patch management, but it is not a monitoring service.
AWS Config is a service that provides a detailed inventory of AWS resources and their configuration history. It can be used to track changes to AWS resources and identify the relationships between them. It is not a monitoring service and does not provide information on EC2 instance limits.
In summary, Amazon CloudWatch is the service that can be used to monitor the number of EC2 instances launched in an AWS account and to provide visibility to understand if the number of EC2 instances approaches the limit set for the account.
