समुच्चय \(A=\{1,2,3\}\) पर संबंध \(R=\{(1,1),(2,2),(3,3),(1,2)\}\) किस गुण को अवश्य संतुष्ट करता है?
On the set \(A=\{1,2,3\}\), the relation \(R=\{(1,1),(2,2),(3,3),(1,2)\}\) must satisfy which property?
Explanation opens after your attempt
Correct Answer
A. प्रतिवर्तीReflexive
Concept
For every \(a\in A\), \((a,a)\in R\), so the relation is reflexive. Symmetry would also require ((2,1)).
Why this answer is correct
The correct answer is A. प्रतिवर्ती / Reflexive. For every \(a\in A\), \((a,a)\in R\), so the relation is reflexive. Symmetry would also require ((2,1)).
Exam Tip
हर \(a\in A\) के लिए \((a,a)\in R\) है इसलिए संबंध प्रतिवर्ती है। सममितता के लिए ((2,1)) भी चाहिए था।
