The application uses a network shared folder as a centralized configuration repository to store configuration files in .xml format. The company is migrating the application to Amazon EC2 instances.

C : Correct — S3 is highly available (99.99%) and durable (11 nines) by design. AWS SDK reads/writes .xml files directly. No infrastructure to manage, most cost-effective, natively multi-AZ.

If linux system and answer has option EFS => EFS. But the question mention about Window system. So answer is option C.
Chose C2
A) Eliminated - We need to deploy and maintain a file system on EBS, which could lead to additional complexity B) Eliminated - Instance store volumes are ephemeral and will be lost if the EC2 instance is stopped or terminated. D) Eliminated - Mounting S3 directly as a volume is not natively supported without third-party solutions or tools like s3fs, which could add unnecessary complexity and overhead.
