यदि \(A=\{1,2,3\}\) और \(B=\{4,5\}\) हैं, तो (A) से (B) में सबसे छोटा संबंध कौन-सा है?
If \(A=\{1,2,3\}\) and \(B=\{4,5\}\), which is the smallest relation from (A) to (B)?
Explanation opens after your attempt
B. \(\varnothing\)
Concept
The smallest subset is \(\varnothing\), so the empty relation is the smallest relation. It is a subset of every \(A\times B\).
Why this answer is correct
The correct answer is B. \(\varnothing\). The smallest subset is \(\varnothing\), so the empty relation is the smallest relation. It is a subset of every \(A\times B\).
Exam Tip
सबसे छोटा उपसमुच्चय \(\varnothing\) होता है, इसलिए खाली संबंध सबसे छोटा संबंध है। यह हर \(A\times B\) का उपसमुच्चय है।
