यदि \(A=\{1,2,3\}\) पर \(R=\{(1,1),(2,2)\}\) है, तो (R) परावर्ती क्यों नहीं है?
If \(R=\{(1,1),(2,2)\}\) on \(A=\{1,2,3\}\), why is (R) not reflexive?
Explanation opens after your attempt
Correct Answer
B. क्योंकि \((3,3)\notin R\)Because \((3,3)\notin R\)
Concept
For a reflexive relation, \((a,a)\in R\) is required for every \(a\in A\). Here \((3,3)\notin R\), so it is not reflexive.
Why this answer is correct
The correct answer is B. क्योंकि \((3,3)\notin R\) / Because \((3,3)\notin R\). For a reflexive relation, \((a,a)\in R\) is required for every \(a\in A\). Here \((3,3)\notin R\), so it is not reflexive.
Exam Tip
परावर्ती संबंध के लिए हर \(a\in A\) पर \((a,a)\in R\) चाहिए। यहाँ \((3,3)\notin R\), इसलिए यह परावर्ती नहीं है।
