A developer is creating an AWS Lambda function to process streaming data from an Amazon Kinesis data stream. When the Lambda function parses the data and encounters a malformed record from the stream, the Lambda function exits with an error.
The developer is observing duplicate records downstream from the function. When the developer uses a different client to examine the Kinesis data stream output, no duplicate records are visible in the stream.
What is the reason for the duplicate records?

A. The Lambda function did not advance the Kinesis data stream pointer to the next record after the error.

B. The Lambda event source used asynchronous invocation.

C. The Lambda function did not handle the error, and the Lambda service attempted to reprocess the data.

D. The Lambda function did not keep up with the amount of data that was coming from the Kinesis data stream.
