यदि \(A=\{p,q,r,s\}\) और \(B=\{p,r\}\) हैं तो (B) के कौन से उपसमुच्चय (A) के भी उपसमुच्चय हैं?
If \(A=\{p,q,r,s\}\) and \(B=\{p,r\}\), which subsets of (B) are also subsets of (A)?
Explanation opens after your attempt
Correct Answer
C. (B) के सभी उपसमुच्चयAll subsets of (B)
Concept
Because \(B\subset A\), every subset of (B) is also a subset of (A). This uses transitive reasoning.
Why this answer is correct
The correct answer is C. (B) के सभी उपसमुच्चय / All subsets of (B). Because \(B\subset A\), every subset of (B) is also a subset of (A). This uses transitive reasoning.
Exam Tip
क्योंकि \(B\subset A\), इसलिए (B) का हर उपसमुच्चय (A) का भी उपसमुच्चय है। यह ट्रांजिटिव सोच का प्रयोग है।
