If (A={1,2,3,4}) and (R={(1,2),(2,1),(2,4),(4,2),(3,3)}), what is the correct conclusion about (R)?

Answer and explanation

Correct answer: (R) is symmetric

Step 1: The reverse of ((1,2)) is ((2,1)), and the reverse of ((2,4)) is ((4,2)). Step 2: ((3,3)) is its own reverse, so it does not break symmetry. Step 3: In exams, check non-diagonal pairs in reverse pairs.
