यदि \(A=\{1,2,3,4\}\) और \(R=\{(1,1),(2,2),(3,3)\}\) है, तो (R) स्वपरावर्ती क्यों नहीं है?
If \(A=\{1,2,3,4\}\) and \(R=\{(1,1),(2,2),(3,3)\}\), why is (R) not reflexive?
Explanation opens after your attempt
B. क्योंकि ( (4,4) ) नहीं हैbecause ( (4,4) ) is absent
Concept
For reflexivity, \((a,a)\in R\) is needed for every \(a\in A\). Here ( (4,4) ) is missing.
Why this answer is correct
The correct answer is B. क्योंकि ( (4,4) ) नहीं है / because ( (4,4) ) is absent. For reflexivity, \((a,a)\in R\) is needed for every \(a\in A\). Here ( (4,4) ) is missing.
Exam Tip
स्वपरावर्ती होने के लिए हर \(a\in A\) के लिए \((a,a)\in R\) चाहिए। यहाँ ( (4,4) ) missing है।
