If (R^{-1}=R), what is the correct conclusion about (R)?

Answer and explanation

Correct answer: (R) is symmetric

Step 1: (R^{-1}=R) means the relation remains the same after reversing all pairs. Step 2: Hence whenever ((a,b)) is present, ((b,a)) is also present. Step 3: This is an equivalent test for symmetry.
