A large global company wants to migrate a stateless mission-critical application to AWS. The application is based on IBM WebSphere (application and integration middleware), IBM MQ (messaging middleware), and IBM DB2 (database software) on a z/OS operating system.
How should the Solutions Architect migrate the application to AWS?

A. Re-host WebSphere-based applications on Amazon EC2 behind a load balancer with Auto Scaling. Re-platform the IBM MQ to an Amazon EC2-based MQ. Re-platform the z/OS-based DB2 to Amazon RDS DB2. B. Re-host WebSphere-based applications on Amazon EC2 behind a load balancer with Auto Scaling. Re-platform the IBM MQ to an Amazon MQ. Re-platform z/ OS-based DB2 to Amazon EC2-based DB2. C. Orchestrate and deploy the application by using AWS Elastic Beanstalk. Re-platform the IBM MQ to Amazon SQS. Re-platform z/OS-based DB2 to Amazon RDS DB2. D. Use the AWS Server Migration Service to migrate the IBM WebSphere and IBM DB2 to an Amazon EC2-based solution. Re-platform the IBM MQ to an Amazon MQ.
