Choose the correct answerWhich of the normal form is based on multivalued dependencies?OptionsSecondFirstThirdFourth

To determine the correct answer, we need to understand which normal form is based on multivalued dependencies.

1. First Normal Form (1NF): This normal form deals with eliminating duplicate data and ensuring atomicity of values in a relation. It does not directly address multivalued dependencies.

2. Second Normal Form (2NF): This normal form deals with eliminating partial dependencies by ensuring that non-key attributes depend on the entire primary key. It does not directly address multivalued dependencies.

3. Third Normal Form (3NF): This normal form deals with eliminating transitive dependencies by ensuring that non-key attributes depend only on the primary key and not on other non-key attributes. It does not directly address multivalued dependencies.

4. Fourth Normal Form (4NF): This normal form specifically addresses multivalued dependencies. It deals with eliminating non-key attributes that depend on other non-key attributes, resulting in a separate relation for each multivalued dependency.

Based on the above information, the correct answer is Fourth.
