यदि \(A\subseteq B\subseteq C\subseteq U\) है, तो पूरकों के लिए कौन सा संबंध सही है?
If \(A\subseteq B\subseteq C\subseteq U\), which relation is correct for complements?
Explanation opens after your attempt
A. \(C^c\subseteq B^c\subseteq A^c\)
Concept
The order of inclusion reverses after taking complements. Hence the complement of the largest set (C) is the smallest.
Why this answer is correct
The correct answer is A. \(C^c\subseteq B^c\subseteq A^c\). The order of inclusion reverses after taking complements. Hence the complement of the largest set (C) is the smallest.
Exam Tip
पूरक लेने पर समावेशन का क्रम उलट जाता है। इसलिए सबसे बड़े (C) का पूरक सबसे छोटा होगा।
