\(यदि (A={1,2,3,4}) और (R={(a,b):a-b\) is divisible by 2}) हो तो (R) के बारे में सही कथन कौन सा है?
\(If (A={1,2,3,4}) and (R={(a,b):a-b\) is divisible by 2}), which statement about (R) is correct?
Explanation opens after your attempt
Correct Answer
A. (R) तुल्य संबंध है(R) is an equivalence relation
Concept
Since (a-a=0), symmetry and transitivity also hold. In exams, always test all three properties for divisibility relations.
Why this answer is correct
The correct answer is A. (R) तुल्य संबंध है / (R) is an equivalence relation. Since (a-a=0), symmetry and transitivity also hold. In exams, always test all three properties for divisibility relations.
Exam Tip
क्योंकि (a-a=0), सममिति और संक्रमणीयता सभी पूरी होती हैं। परीक्षा में भाग्यता वाले संबंधों में तीनों गुण जरूर जांचें।
