Which attributes are considered prime attributes in a relation?Attributes that are part of any candidate keyAttributes that are part of the primary keyAttributes that are not involved in any functional dependencyAttributes that uniquely identify each tuple in the relationExplanation for answerReview AnswerNext

Prime attributes in a relation are those attributes that are part of any candidate key. A candidate key is a set of one or more attributes that can uniquely identify a tuple (row) in a relation (table).

Here are the steps to identify prime attributes:

1. Identify all candidate keys in the relation. A candidate key can be a single attribute or a combination of attributes that uniquely identify a tuple in the relation.

2. Any attribute that is part of a candidate key is a prime attribute.

So, the attributes that are part of the primary key are also considered prime attributes because the primary key is a candidate key. However, not all prime attributes need to be part of the primary key.

Attributes that are not involved in any functional dependency are not necessarily prime attributes. A prime attribute can be involved in a functional dependency as long as it's on the left-hand side (the determining side) of the functional dependency.

Finally, while it's true that prime attributes uniquely identify each tuple in the relation, it's important to note that they do this as part of a candidate key. A single prime attribute does not necessarily uniquely identify each tuple unless that attribute is itself a candidate key.
