Correct answer: C. File anomaly
- A. Insertion anomaly
- B. Deletion anomaly
- C. File anomaly
- D. Modification anomaly
Explanation
File anomaly is not a standard type of anomaly in relational databases. "File" is a general term for a computer storage location and doesn't directly relate to the concept of anomalies arising from data relationships. In relational database design, we strive to normalize the database structure to minimize these anomalies and ensure data integrity

About Databases
Databases cover tables, records, fields, keys and relationships, together with database management systems and relational database design. The subject includes primary and foreign keys, normalization, SQL commands such as SELECT, INSERT, UPDATE and DELETE, queries, forms and reports, while distinguishing a database from a spreadsheet used for simple tabular data.
