(i) First Normal Form (1NF)
(ii) Second Normal Form (2NF)

Explanation
(PICK ANY ONE)
(i) First Normal Form (1NF): In 1NF, each attribute in a table must contain atomic values, meaning each field must hold a single value and cannot be further divided. This eliminates repeating groups and ensures data integrity by organizing data into distinct and unambiguous entities.
(ii) Second Normal Form (2NF): 2NF builds on 1NF by ensuring that each non-key attribute is fully functionally dependent on the primary key. This means that each non-key attribute must be dependent on the entire primary key, not just part of it, to prevent partial dependencies and maintain data consistency.
