यदि \(R=\{(2,5),(5,2),(3,4)\}\) है, तो (R) सममित क्यों नहीं है?
If \(R=\{(2,5),(5,2),(3,4)\}\), why is (R) not symmetric?
Explanation opens after your attempt
C. ( (4,3) ) missing है( (4,3) ) is missing
Concept
Here \((3,4)\in R\), but \((4,3)\notin R\). One missing reverse pair makes the relation non-symmetric.
Why this answer is correct
The correct answer is C. ( (4,3) ) missing है / ( (4,3) ) is missing. Here \((3,4)\in R\), but \((4,3)\notin R\). One missing reverse pair makes the relation non-symmetric.
Exam Tip
\((3,4)\in R\) है लेकिन \((4,3)\notin R\) है। एक reverse pair missing होने से relation symmetric नहीं होता।
