यदि \(A=\{1,2,3\}\) पर \(R=\varnothing\) हो तो कौन सा कथन सही है?
If \(R=\varnothing\) on \(A=\{1,2,3\}\), which statement is correct?
Explanation opens after your attempt
Correct Answer
B. (R) रिक्त संबंध है(R) is the empty relation
Concept
There is no ordered pair in \(\varnothing\), so it is the empty relation. Since \(A\neq\varnothing\), it is not reflexive.
Why this answer is correct
The correct answer is B. (R) रिक्त संबंध है / (R) is the empty relation. There is no ordered pair in \(\varnothing\), so it is the empty relation. Since \(A\neq\varnothing\), it is not reflexive.
Exam Tip
\(\varnothing\) में कोई क्रमित युग्म नहीं होता इसलिए यह रिक्त संबंध है। \(A\neq\varnothing\) होने पर यह प्रतिवर्ती नहीं है।
