Question: Which of the following statements regarding SQL normalization and its levels is correct?

A) Normalization is the process of denormalizing data to improve query performance by combining multiple tables into one.
B) The first normal form (1NF) requires that all columns in a table contain atomic values and that each column contains unique values.
C) The second normal form (2NF) builds on the first normal form by ensuring that all non-key attributes are fully functionally dependent on the primary key.
D) The third normal form (3NF) allows transitive dependencies among non-key attributes, provided they are all unique.
