C.

Convert the Kinesis consumer application to run as an AWS Lambda function. Configure the Kinesis data streams as the event source for the Lambda function to process the data streams

D.

Increase the number of shards in the Kinesis data streams to increase the overall throughput so that the consumer application processes the data faster.
