On (A={1,2,3}), (R) is reflexive and ((1,2)\notin R). Which conclusion is correct?

Answer and explanation

Correct answer: This does not contradict reflexivity

Step 1: Reflexivity makes only self-pairs compulsory. Step 2: ((1,2)) is a non-diagonal pair, so its absence does not break reflexivity. Step 3: In exams, do not treat non-diagonal pairs as compulsory.
