If a relation on (A={1,2,3,4}) has only ((1,1),(2,2),(3,3),(4,4)), what is it called?

Answer and explanation

Correct answer: Identity relation

Step 1: Pairs only of the form ((a,a)) make the identity relation. Step 2: Here every element has its self-pair. Step 3: The identity relation is reflexive, but every reflexive relation need not be only identity.
