समुच्चय \(A=\{1,2,3\}\) पर संबंध \(R=\{(1,1),(2,2)\}\) प्रतिवर्ती क्यों नहीं है?
Why is the relation \(R=\{(1,1),(2,2)\}\) on \(A=\{1,2,3\}\) not reflexive?
Explanation opens after your attempt
Correct Answer
B. क्योंकि \((3,3)\notin R\)Because \((3,3)\notin R\)
Concept
For reflexivity, \((a,a)\in R\) must hold for every \(a\in A\). Here ((3,3)) is missing.
Why this answer is correct
The correct answer is B. क्योंकि \((3,3)\notin R\) / Because \((3,3)\notin R\). For reflexivity, \((a,a)\in R\) must hold for every \(a\in A\). Here ((3,3)) is missing.
Exam Tip
प्रतिवर्ती होने के लिए हर \(a\in A\) पर \((a,a)\in R\) होना चाहिए। यहां ((3,3)) अनुपस्थित है।
