B is correct ❌ D — API Gateway + Kinesis Data Analytics real-time stream processing / analytics It isn't the normal storage/retrieval layer for an application's REST API.
Why D is correct: API Gateway provides the REST API layer — bikes (or the mobile app) send location updates via REST, and the data can be queried via REST Kinesis Data Analytics is purpose-built to process and analyze streaming data in real time (using SQL or Apache Flink). Continuous location pings are the textbook streaming use case API Gateway can act as a direct proxy into the Kinesis family, so the tiers connect natively
Amazon API Gateway + Amazon Kinesis Data Analytics is the right combination for this use case because it addresses both the real-time streaming nature of bicycle location data and the REST API accessibility requirement.
