On (A={1,2,3}), (R={(1,1),(2,2),(3,3),(1,2),(2,1),(2,3),(3,2)}) is given. Which pairs are definitely needed to make it an equivalence relation?

Answer and explanation

Correct answer: ((1,3)) and ((3,1))

Step 1: The relation is reflexive and appears symmetric, but transitivity must be checked. Step 2: From ((1,2)) and ((2,3)), ((1,3)) is needed; from ((3,2)) and ((2,1)), ((3,1)) is needed. Step 3: In an equivalence relation, all elements of the same class must be mutually related.
