यदि \(A\subseteq B\), \(B\subseteq C\) और (A=C) हैं तो (A,B,C) के बारे में कौन सा निष्कर्ष सही है?
If \(A\subseteq B\), \(B\subseteq C\), and (A=C), then which conclusion about (A,B,C) is correct?
Explanation opens after your attempt
A. (A=B=C)
Concept
(B) lies between (A) and (C), and (A=C), so (B) must also be equal to them. In subset chains, check equality conditions carefully.
Why this answer is correct
The correct answer is A. (A=B=C). (B) lies between (A) and (C), and (A=C), so (B) must also be equal to them. In subset chains, check equality conditions carefully.
Exam Tip
(B) (A) और (C) के बीच है और (A=C) है, इसलिए (B) भी उसी के बराबर होगा। उपसमुच्चय शृंखला में बराबरी की स्थिति ध्यान से देखें।
