Which solution will meet these requirements? A. Use Amazon Kinesis Data Firehose to send the data to Amazon Redshift. B. Use Amazon Kinesis Data Streams to send the data to Amazon DynamoDB. C. Use Amazon Managed Streaming for Apache Kafka (Amazon MSK) to send the data to Amazon Aurora. D. Use Amazon Kinesis Data Firehose to send the data to Amazon Keyspaces (for Apache Cassandra).
