An Alexa Skill Builder is developing a custom skill and needs to verify that the correct slot values are being passed into the AWS Lambda function.

According to best practices, what is the MOST efficient way to capture this information?

A. Add a logging statement to write the event request to Amazon CloudWatch Logs.
B. Add an API call to write the environment variables to an Amazon S3 bucket when the function is invoked.
C. Add an API call to read the event information from AWS Cloud Trail logs and add a PutObject API call to write to an Amazon S3 bucket.

D. Add a statement to parse the JSON request and save to the local disk for the Lambda function
