Which relation is definitely symmetric?

Answer and explanation

Correct answer: (R={(a,b):a^2=b^2}) on real numbers

Step 1: If (a^2=b^2), then (b^2=a^2) is also certainly true. Step 2: Hence ((a,b)) implies ((b,a)). Step 3: Conditions based on equality are often symmetric, while inequalities or divisibility need separate checking.
