Suggested answer: A

Explanation:

https://docs.aws.amazon.com/lambda/latest/dg/nodejs-context.html

https://docs.aws.amazon.com/lambda/latest/dg/nodejs-logging.html

There is no explicit information for the runtime, the code is written in Node.js. AWS Lambda is a service that lets developers run code without provisioning or managing servers.

The developer can use the AWS request ID field in the context object to obtain a unique identifier for each function invocation. The developer can configure the application to write logs to standard output, which will be captured by Amazon CloudWatch Logs. This solution will meet the requirement of logging key events with a unique identifier.
