If (A) is non-empty and (R) is reflexive on (A), which statement about (A\times A-R) is correct?

Answer and explanation

Correct answer: It cannot be reflexive

Step 1: Since (R) is reflexive, ((a,a)\in R) for every (a\in A). Step 2: In (A\times A-R), all pairs of (R) are removed, so the self-pairs are removed. Step 3: On a non-empty set, a relation without self-pairs cannot be reflexive.
