What is data in a MySQL database organized into?

In a MySQL database, data is organized into tables.
Tables consist of rows and columns, where each row represents a record and each column represents a field or attribute of the record.
Option A, Objects, is incorrect because while MySQL databases can be object-oriented in nature, the primary organizational structure for data is tables, not objects.
Option C, Networks, is incorrect because MySQL databases do not organize data into networks; rather, they use tables to structure the data.
Option D, File systems, is incorrect because although MySQL stores data on a file system, the organization and retrieval of data within MySQL databases are primarily through tables, not directly through the file system.
