यदि \(R=\{(1,2),(2,1)\}\) है और आधार set \(A=\{1,2\}\) है, तो (R) स्वपरावर्ती क्यों नहीं है?
If \(R=\{(1,2),(2,1)\}\) and the base set is \(A=\{1,2\}\), why is (R) not reflexive?
Explanation opens after your attempt
C. ( (1,1) ) और ( (2,2) ) missing हैं( (1,1) ) and ( (2,2) ) are missing
Concept
A reflexive relation needs all diagonal pairs. Here ( (1,1) ) and ( (2,2) ) are absent.
Why this answer is correct
The correct answer is C. ( (1,1) ) और ( (2,2) ) missing हैं / ( (1,1) ) and ( (2,2) ) are missing. A reflexive relation needs all diagonal pairs. Here ( (1,1) ) and ( (2,2) ) are absent.
Exam Tip
Reflexive relation में सभी diagonal pairs चाहिए। यहाँ ( (1,1) ) और ( (2,2) ) नहीं हैं।
