Which of the following data models stores data in rows and columns?

Explanation

The correct answer is C. Relational data model.Relational data models store data in two-dimensional tables with rows and columns. Each table represents a specific entity or concept, and each row (also called a tuple) represents a record or instance of that entity. Columns (also called attributes) define the characteristics or properties of the entity.Here's why the other options are incorrect:A. Network data model stores data in a more complex structure where records can have multiple parent records. It doesn't use a simple tabular format with rows and columns.B. Object data model represents data using objects, which encapsulate data and the associated operations. While objects can have properties and methods similar to table columns, they don't directly map to a row-and-column structure.D. Hierarchical data model organizes data in a tree-like structure where child records are linked to a single parent record. This parent-child hierarchy differs from the two-dimensional table format used in relational models.
