Answer: D

Explanation:

Amazon MQ, Amazon SQS, and Amazon SNS are messaging services that are suitable for anyone from startups to enterprises. If you’re using messaging with existing applications and want to move your messaging service to the cloud quickly and easily, it is recommended that you consider Amazon MQ. It supports industry-standard APIs and protocols so you can switch from any standards-based message broker to Amazon MQ without rewriting the messaging code in your applications. Hence, Amazon MQ is the correct answer.

If you are building brand new applications in the cloud, then it is highly recommended that you consider Amazon SQS and Amazon SNS. Amazon SQS and SNS are lightweight, fully managed message queue and topic services that scale almost infinitely and provide simple, easy-to-use APIs. You can use Amazon SQS and SNS to decouple and scale microservices, distributed systems, and serverless applications, and improve reliability.

Amazon SQS is incorrect. Although this is a fully managed message queuing service, it does not support an extensive list of industry-standard messaging APIs and protocol, unlike Amazon MQ. Moreover, using Amazon SQS requires you to do additional changes in the messaging code of applications to make it compatible.

Amazon SNS is incorrect because SNS is more suitable as a pub/sub messaging service instead of a message broker service.

Amazon SWF is incorrect because this is a fully-managed state tracker and task coordinator service and not a messaging service, unlike Amazon MQ, AmazonSQS and Amazon SNS. References:
