A relation is in 2NF if it is in 1NF and all its non-key attributes are
Correct answer: B. Dependent on the entire primary key
- A. Dependent on part of the primary key
- B. Dependent on the entire primary key
- C. Independent of the primary key
- D. Independent of any other relation
Explanation
A relation is in Second Normal Form (2NF) if it satisfies two conditions:1. It is already in First Normal Form (1NF), meaning there are no repeating groups and all attributes contain atomic values (indivisible units of data).Every non-key attribute is fully dependent on the entire primary key. This eliminates partial dependencies, where a non-key attribute relies on only a part of the composite primary key

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.
