Let A be a non-empty set and R a relation on A. R is called irreflexive if (aa)ER for all aEA. Let z be the set of integers and R be the relation on Z defined as follows: aRb if and only if a(mod 3) = (b+1) (mod 3).Then O Ris an equivalence relation O Ris not an irreflexive relation and not a reflexive relation Ris an irreflexive relation None of these
