Correct Answer

A. हर pair अपना reverse खुद हैeach pair is its own reverse

Explanation

Simple Explanation

Diagonal pair ( (a,a) ) का reverse भी ( (a,a) ) ही होता है। इसलिए केवल diagonal pairs वाला relation symmetric है। / The reverse of a diagonal pair ( (a,a) ) is the same pair ( (a,a) ). Hence a relation with only diagonal pairs is symmetric.
