If (R={(1,1),(2,2),(3,3),(1,2),(2,1)}), what type is (R) on (A={1,2,3})?

Answer and explanation

Correct answer: Reflexive and symmetric

Step 1: All diagonal pairs ((1,1),(2,2),(3,3)) of (A) are present, so the relation is reflexive. Step 2: Both ((1,2)) and ((2,1)) are present, so it is also symmetric. Step 3: When two properties are asked, verify both fully.
