If a relation contains ((2,5)) but does not contain ((5,2)), which conclusion is definite?

Answer and explanation

Correct answer: The relation is not symmetric

Step 1: Symmetry requires the reverse of every present pair to be present. Step 2: ((2,5)) is present, but ((5,2)) is not. Step 3: This single missing reverse pair is enough to show the relation is not symmetric.
