If in an arrow diagram for (A={1,2,3}), only (1) and (2) have arrows to themselves, but (3) does not, what is the relation?

Answer and explanation

Correct answer: Not reflexive

Step 1: A reflexive relation needs a self-arrow at every element. Step 2: Element (3) has no such arrow, so ((3,3)) is missing. Step 3: If one point lacks a loop, reflexivity fails.
