We cannot connect the dynamo db directly to the Kinesis fire hose, so we need the Kinesis streams and lambda function to enrich the data.

This, The fact it asks for enrichment is why it is B. Either way it requires a Lambda function vote for B.

D Kinesis Data Firehose can invoke your Lambda function to transform incoming source data and deliver the transformed data to destinations. You can enable Kinesis Data Firehose data transformation when you create your delivery stream.

Selected Answer: B
The wording may be wrong as it sounds like the lambda is not invoked between the two streams, but having two streams is mandatory. D is written like it is a single stream which will not work.
