If a relation (R) is symmetric, which of the following is not necessary?

Answer and explanation

Correct answer: For every (a\in A), ((a,a) \in R)

Step 1: Having every ((a,a)) is related to reflexivity. Step 2: Symmetry only says that the reverse of every present pair must also be present. Step 3: Keep reflexive and symmetric properties separate in exams.
