यदि \(A\subseteq U\), \(B\subseteq U\), और \(A\subseteq B\) है, तो पूरकों के लिए कौन सा संबंध सही है?
If \(A\subseteq U\), \(B\subseteq U\), and \(A\subseteq B\), which relation is correct for complements?
Explanation opens after your attempt
Correct Answer
B. \(B'\subseteq A'\)
Concept
If \(A\subseteq B\), then every element outside (B) is also outside (A). Hence \(B'\subseteq A'\).
Why this answer is correct
The correct answer is B. \(B'\subseteq A'\). If \(A\subseteq B\), then every element outside (B) is also outside (A). Hence \(B'\subseteq A'\).
Exam Tip
यदि \(A\subseteq B\) है, तो (B) के बाहर के तत्व (A) के बाहर भी होंगे। इसलिए \(B'\subseteq A'\) होता है।
