यदि \(A\subseteq U\) और (A'=U) है, तो (A) क्या होगा?
If \(A\subseteq U\) and (A'=U), what is (A)?
Explanation opens after your attempt
B. \(\varnothing\)
Concept
If the complement of (A) is the whole (U), then (A) cannot contain any element. Hence \(A=\varnothing\).
Why this answer is correct
The correct answer is B. \(\varnothing\). If the complement of (A) is the whole (U), then (A) cannot contain any element. Hence \(A=\varnothing\).
Exam Tip
यदि (A) का पूरक पूरा (U) है, तो (A) में कोई तत्व नहीं हो सकता। इसलिए \(A=\varnothing\) है।
