Answer: Cloud Datastore
The correct choice is **A (Cloud Datastore)** because it offers a scalable, fully managed NoSQL document database ideal for web and mobile applications. It supports semistructured application data, user profiles, hierarchical data, product catalogs, and durable key-value data, making it perfect for stateful data storage with the ability to scale down to zero. - **B (Cloud Bigtable)** is incorrect as it's designed for low-latency single-point lookups and precalculated analytics, not state management. - **C (Cloud Dataproc)** is incorrect because it's a service for running Apache Spark and Apache Hadoop clusters, not a storage solution. - **D (Cloud SQL)** is incorrect as it requires capacity provisioning and is a managed MySQL and PostgreSQL database service, not suited for non-relational data or scaling down to zero.
