A company has deployed a serverless application that invokes an AWS Lambda function when new documents are uploaded to an Amazon S3 bucket. The application uses the Lambda function to process the documents. After a recent marketing campaign, the company noticed that the application did not process many of the documents. What should a solutions architect do to improve the architecture of this application?

• ASet the Lambda function's runtime timeout value to 15 minutes.
• BConfigure an S3 bucket replication policy. Stage the documents in the S3 bucket for later processing.
• CDeploy an additional Lambda function. Load balance the processing of the documents across the two Lambda functions.
• DCreate an Amazon Simple Queue Service (Amazon SQS) queue. Send the requests to the queue. Configure the queue as an event source for Lambda.
