The correct answer is Relational database model.

The Relational database model arranges data into tables made up of rows and columns and each column represents an attribute or field of the data element. This model enforces a schema and typed fields so records are explicitly organized into fields that reflect the attributes of each element and the model is the clear match for the description in the question.

Google Cloud Bigtable is a wide column NoSQL store that uses sparse, distributed tables and flexible column families rather than a fixed set of fields per record, so it does not follow the classic relational fields and schema model.

Object storage stores whole objects with metadata and is optimized for unstructured or binary data, so it does not organize records into fields and columns like a relational database does.

Raw block storage provides raw block devices without any inherent data schema and it is used as a low level volume for filesystems or databases, so it does not itself arrange records into attribute fields.
