Functional dependency refers to a relationship between two entities in which the value of one entity (dependent entity) is determined based on the value of another entity (independent entity). In other words, when we are given the value of the independent entity, we can determine the value of the dependent entity. This is expressed in option B. The other options are not necessarily true for all cases of functional dependency.
