A relation (R) on a set (A) is symmetric. Which of the following need not be true?

Answer and explanation

Correct answer: हर (a \in A) के लिए ((a,a) \in R)

Step 1: Symmetry only demands reverse pairs for pairs that are present. Step 2: Having every ((a,a)) is the condition for reflexivity, not symmetry. Step 3: Keeping definitions separate helps solve such trap questions.
