यदि \(A=\{1,2,3\}\) और \(R=\{(1,2),(2,1),(2,3),(3,2)\}\) हो तो (R) किस गुण को संतुष्ट करता है?
If \(A=\{1,2,3\}\) and \(R=\{(1,2),(2,1),(2,3),(3,2)\}\), which property does (R) satisfy?
Explanation opens after your attempt
Correct Answer
B. सममितSymmetric
Concept
For every \((a,b)\in R\), \((b,a)\in R\) is also present, so it is symmetric. To be reflexive, it needs ((1,1),(2,2),(3,3)).
Why this answer is correct
The correct answer is B. सममित / Symmetric. For every \((a,b)\in R\), \((b,a)\in R\) is also present, so it is symmetric. To be reflexive, it needs ((1,1),(2,2),(3,3)).
Exam Tip
हर \((a,b)\in R\) के साथ \((b,a)\in R\) भी है इसलिए यह सममित है। प्रतिवर्ती होने के लिए ((1,1),(2,2),(3,3)) चाहिए।
