यदि \(A=\{1,2,3\}\) और \(R=\{(1,1),(2,2)\}\) है, तो (R) reflexive क्यों नहीं है?
If \(A=\{1,2,3\}\) and \(R=\{(1,1),(2,2)\}\), why is (R) not reflexive?
Explanation opens after your attempt
C. क्योंकि ( (3,3) ) नहीं हैbecause ( (3,3) ) is absent
Concept
For reflexive relation, ( (3,3) ) must also be present. If one diagonal pair is missing, the relation is not reflexive.
Why this answer is correct
The correct answer is C. क्योंकि ( (3,3) ) नहीं है / because ( (3,3) ) is absent. For reflexive relation, ( (3,3) ) must also be present. If one diagonal pair is missing, the relation is not reflexive.
Exam Tip
Reflexive होने के लिए ( (3,3) ) भी होना चाहिए। एक diagonal pair missing हो तो relation reflexive नहीं होता।
