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
Correct Answer

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

Step 1

Concept

Here \((3,4)\in R\), but \((4,3)\notin R\). One missing reverse pair makes the relation non-symmetric.

Step 2

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.

Step 3

Exam Tip

\((3,4)\in R\) है लेकिन \((4,3)\notin R\) है। एक reverse pair missing होने से relation symmetric नहीं होता।
