Multiple Choice

A company has an application that logs all information to Amazon S3. Whenever there is a new log file, an AWS Lambda function is invoked to process the log files. The code works, gathering all of the necessary information. However, when checking the Lambda function logs, duplicate entries with the same request ID are found. What is causing the duplicate entries?

A) The S3 bucket name was specified incorrectly.
B) The Lambda function failed, and the Lambda service retried the invocation with a delay.
C) There was an S3 outage, which caused duplicate entries of the sale log file.
D) The application stopped intermittently and then resumed.
