Option D is the correct answer. Amazon Kinesis Data Streams is designed to handle large-scale, real-time data streaming, making it ideal for collecting clickstream data. Amazon Kinesis Data Firehose can then be used to automatically deliver the data to an Amazon S3 data lake. This setup simplifies the data transmission process. Once the data is in S3, Amazon Redshift can efficiently load and analyze the data, providing powerful analytics capabilities. This solution leverages managed AWS services that are scalable and cost-effective, ensuring reliable and real-time processing of large datasets.
