Structured data is characterized by:

Structured data is characterized by being held in a pre-existing format that is easy to search. This type of data is organized in a predictable manner, often stored in databases or spreadsheets, and follows a defined model or schema. Examples include data in tables with rows and columns, where each field represents a specific type of information, such as names, dates, or monetary values.

The organized nature of structured data allows for efficient querying and data management, enabling users to easily retrieve and analyze information. This makes it highly suitable for applications that require straightforward analysis, such as business intelligence or reporting.

In contrast, the other choices refer to traits of unstructured or semi-structured data, which lack a defined format and can be harder to process or analyze without additional effort. Thus, the characteristics highlighted in the correct answer emphasize the reasons why structured data is valued in data management and analysis contexts.
