Final answer:

O yes, it is in 3nf. A dataset is in 3NF if it satisfies certain conditions related to functional dependencies.

Step-by-step explanation:

In order to determine if a dataset is in third normal form (3NF), we need to analyze the functional dependencies within the dataset. A functional dependency occurs when one attribute determines another attribute, meaning that the value of one attribute uniquely determines the value of another attribute.

If there is an issue with the functional dependency in the dataset, it means that the dataset is not in 3NF. This could be due to attributes depending on part of a composite key or transitive dependencies. For example, if there is an attribute that depends on only a part of a composite key, it violates the 3NF.

Therefore, we cannot determine if the dataset is in 3NF based solely on the given options in the question. We need more information about the dataset and its functional dependencies to make a conclusion.
