According to Amazon Alexa best practices, how should an Alexa Skill Builder prevent unintentional requests against a skill's backend when using AWS Lambda?
- A.Ensure that the session ID provided by the request to Lambda is not already in use.
- B.Rotate the Lambda ARN regularly to prevent others from using the service.
- C.Retrieve the Application ID property from the request JSON and validate it against the Lambda environment variables.
- D.Provide the Lambda trigger with the Application ID so that it validates on the ask trigger.
