    The answer is option A) Attributes of different entities should not be mixed in the same relation.

    Explanation:

    A tuple is a set of attribute values in which no two distinct elements have the same name. Thus, in some accounts, a tuple is described as a function mapping names to values.

    An attribute value is an attribute name paired with an element of that attribute's domain.

    Informally, each tuple in a relation should represent one entity or relationship instance.

    Therefore, attributes of different entities should not be mixed in the same relation.
