On (A={1,2,3,4}), what are the equivalence classes of the identity relation (I={(1,1),(2,2),(3,3),(4,4)})?

Answer and explanation

Correct answer: ({1},{2},{3},{4})

Step 1: In the identity relation, every element is related only to itself. Step 2: Hence each element forms a separate singleton class. Step 3: The number of classes in an identity relation equals the number of elements.
