Click on the arrows to vote for the correct answer
A. B. C. D.Correct Answer: A.
Option A is correct.
Firestore is a Google product that is scalable, requires no maintenance, and it is a serverless document database.
Option B is incorrect.
Cloud Spanner is incorrect because it is a relational database service, not a document database.
Option C is incorrect.
Memorystore, also known as Memorystore for Redis, is a fully managed Google's in-memory data store service.
Option D is incorrect.
Cloud Bigtable is a big data database service, not a document database.

Here's why:
A) Firestore: Firestore is a fully managed NoSQL document database that can be used for web and mobile applications. Firestore is designed to scale automatically to handle large amounts of data and traffic. It is a serverless service, which means that there are no servers to manage or configure. Firestore can also handle complex queries and transactions.
Firestore is also a document database, which means that it stores data in documents. Each document can contain nested sub-collections and fields, making it a flexible and scalable option for storing structured data. Firestore also provides strong consistency, which ensures that all clients see the same data at the same time.
B) Cloud Spanner: Cloud Spanner is a distributed, horizontally scalable relational database service that is designed to handle global-scale transactions and strong consistency. It is a fully managed service that is serverless. However, it is a relational database, which means that it may not be the best option for a document-based database.
C) Memorystore: Memorystore is a fully managed in-memory data store service that is used for caching and fast data access. It is not designed for document-based data storage and is not a suitable option for this use case.
D) Cloud Bigtable: Cloud Bigtable is a fully managed NoSQL database service that is designed for large-scale, low-latency, and high-throughput workloads. It is a suitable option for storing large amounts of unstructured data, such as time-series data or sensor data. However, it is not a document-based database, and may not be the best option for this use case.
In summary, Firestore is the best option for a scalable, no-maintenance, and serverless document database. It is designed for web and mobile applications, can handle complex queries and transactions, and provides strong consistency.
