Answer: NoSQL
The correct answer is **B. NoSQL**, as solutions like Bigtable and Datastore are ideal for storing sensor ID and various discrete data points. They also enable data joining with other sources and can be configured for multi-region data storage. Refer to GCP documentation on Storage Options for more details. - **Option A (Blobstore)** is incorrect because blob storage, such as Cloud Storage, is not suited for storing, analyzing schema-less data, or joining with other data sources. - **Option C (Relational)** is incorrect because relational databases like Cloud SQL are not ideal for schema-less data. - **Option D (Flat file)** is incorrect due to its lack of scalability.
