B) Use a CloudWatch Logs subscription to trigger an AWS Lambda function to send the log data to an Amazon Kinesis Data Firehose stream that has an Amazon S3 bucket destination. Use a new Amazon Redshift cluster and Amazon Redshift Spectrum to query the log data from the bucket.
C) Use a CloudWatch Logs subscription to send the log data to an Amazon Kinesis Data Firehose stream that has an Amazon S3 bucket destination. Use Amazon Athena to query the log data from the bucket.
