Is the relation (R={(1,1),(1,2),(2,1),(2,3),(3,2)}) symmetric or not?

Answer and explanation

Correct answer: Yes, because all given pairs have their reverses

Step 1: The reverse of ((1,1)) is itself. Step 2: ((1,2)) is matched by ((2,1)), and ((2,3)) is matched by ((3,2)). Step 3: Symmetry does not require all ((a,a)) pairs to be present.
