Yоu аre wоrking аs а database architect fоr DataSphere Ltd. and are tasked with designing a relational database for the company's project management system. To ensure the database is in Third Normal Form (3NF), you need to carefully follow the normalization steps outlined below: Identify all transitive dependencies where non-prime attributes depend on other non-prime attributes. Create a new table for each transitive dependency, including the determinant and the attributes it determines. Ensure the determinant becomes the primary key of the new table. Remove the transitive dependencies from the original table and reference the new table using a foreign key. Which of the following is the correct sequence to achieve 3NF normalization?

However, the question is asking about all subsets that can potentially act as primary keys.
