Why is (R={(1,1),(2,2)}) not reflexive on (A={1,2,3})?

Answer and explanation

Correct answer: Because ((3,3)) is missing

Step 1: A reflexive relation must contain each element paired with itself. Step 2: Here ((3,3)) is missing, so the relation is not reflexive. Step 3: Check every element separately for reflexivity.
