In a relation, if ((4,4)) is missing and (4\in A), what conclusion follows?

Answer and explanation

Correct answer: The relation is not reflexive

Step 1: Since (4\in A), reflexivity requires ((4,4)). Step 2: This pair is missing, so the condition fails. Step 3: In checking reflexivity, any missing diagonal pair gives the answer quickly.
