Answer: Set a Lambda function destination for failed invocations, using the error-handling function's ARN.
The correct answer is A. AWS Lambda destinations allow you to specify what should happen with the invocation records of your Lambda functions depending on whether the invocation was successful or failed. By configuring a Lambda function destination for failed invocations, you can direct the failed invocation records to another Lambda function specified by its Amazon Resource Name (ARN). This setup doesn't require changes to the application code and automatically handles errors, making option A the most suitable and efficient solution.
