Explain the concept of a reflexive relation and provide an example.
A reflexive relation is a binary relation on a set where every element is related to itself. In other words, for every element "a" in the set, the relation contains the pair (a, a). This property of reflexivity is an important concept in mathematics and computer science, particularly in the study of computational complexity theory.
