यदि \(A=\{1,2,{3}\}\) है तो कौन सा (A) का उपसमुच्चय है?
If \(A=\{1,2,{3}\}\) then which is a subset of (A)?
Explanation opens after your attempt
A. ({1,{3}})
Concept
Both (1) and ({3}) are elements of (A). Since (3) itself is not in (A), options using it may be false.
Why this answer is correct
The correct answer is A. ({1,{3}}). Both (1) and ({3}) are elements of (A). Since (3) itself is not in (A), options using it may be false.
Exam Tip
(1) और ({3}) दोनों (A) के अवयव हैं। (3) स्वयं (A) में नहीं है इसलिए उससे बने विकल्प गलत हो सकते हैं।
