Which actions will diagnose and resolve the delay?

An ecommerce company is receiving reports that its order history page is experiencing delays in reflecting the processing status of orders. The order processing system consists of an AWS Lambda function using reserved concurrency. The Lambda function processes order messages from an Amazon SQS queue and inserts processed orders into an Amazon DynamoDB table. The DynamoDB table has Auto Scaling enabled for read and write capacity.

Which actions will diagnose and resolve the delay? (Select TWO.)
A . Check the ApproximateAgeOfOldestMessage metric for the SQS queue and increase the Lambda function concurrency limit.
B. Check the ApproximateAgeOfOldestMessage metric for the SQS queue and configure a redrive policy on the SQS queue.
C. Check the NumberOfMessagesSent metric for the SQS queue and increase the SQS queue visibility timeout.
D. Check the ThrottledWriteRequests metric for the DynamoDB table and increase the maximum write capacity units for the table’s Auto Scaling policy.
E. Check the Throttles metric for the Lambda function and increase the Lambda function timeout.
