Correct Answer

C. ( (4,3) ) missing है( (4,3) ) is missing

Explanation

Simple Explanation

\((3,4)\in R\) है लेकिन \((4,3)\notin R\) है। एक reverse pair missing होने से relation symmetric नहीं होता। / Here \((3,4)\in R\), but \((4,3)\notin R\). One missing reverse pair makes the relation non-symmetric.
