A Company has two batch processing applications that consume financial data about the day's stock transactions. Each transaction needs to be stored durably and guarantee that a record of each application is delivered so the audit and billing batch processing applications can process the data. However, the two applications run separately and several hours apart and need access to the same transaction information. After reviewing the transaction information for the day, the information no longer needs to be stored. What is the best way to architect this application? Choose the correct answer from the options below

A. Use SQS for storing the transaction messages. When the billing batch process consumes each message, have the application create an identical message and place it in a different SQS for the audit application to use several hours later.

B. Use SQS for storing the transaction messages; when the billing batch process performs first and consumes the message, write the code in a way that does not remove the message after consumed, so it is available for the audit application several hours later. The audit application can consume the SQS message and remove it from the queue when completed.

C. Store the transaction information in a DynamoDB table. The billing application can read the rows while the audit application will read the rows them remove the data.

D. Use Kinesis to store the transaction information. The billing application will consume data from the stream, the audit application can consume the same data several hours later.
