यदि \(A=\{p,q,r\}\) है तो कौन सा (A) का उपसमुच्चय नहीं है?
If \(A=\{p,q,r\}\) then which is not a subset of (A)?
Explanation opens after your attempt
C. ({p,s})
Concept
({p,s}) contains (s) which is not in (A). Even one outside element makes it not a subset.
Why this answer is correct
The correct answer is C. ({p,s}). ({p,s}) contains (s) which is not in (A). Even one outside element makes it not a subset.
Exam Tip
({p,s}) में (s) है जो (A) में नहीं है। एक भी बाहरी अवयव होने पर उपसमुच्चय नहीं बनता।
