Explanation

Changing an EC2 instance type requires the instance to be in a stopped state-AWS cannot resize a running instance. Because the SAP application is running on that instance, the correct procedure is: (1) perform a clean SAP system shutdown to avoid data corruption or open transactions, (2) stop the EC2 instance through the console or CLI, (3) modify the instance type to c5a.2xlarge, and (4) start the instance and restart SAP. Options B and D are incorrect because instance type changes cannot be made while the instance is running. Option C (terminate) would permanently destroy the instance, making it the wrong approach when a simple stop-modify-start cycle is sufficient.
