Final Answer:
Like most databases, the data in library databases is organized into fields for each entry. Option B is answer.
Step-by-step explanation:
In the context of databases, particularly library databases, information for each entry is structured and organized into fields. A field is a specific piece of information or attribute associated with a record or entry in a database.
These fields represent different aspects or properties of the entry, such as title, author, publication date, and so on. Each field contains a specific type of data and contributes to the overall organization and categorization of the database.
While categories, keywords, and sections are relevant concepts in information organization, they don't specifically represent the individual units within a database entry.
Therefore, option B, "fields," is the correct answer.
