यदि \(A\subseteq U\) और \(A'= \varnothing\) है, तो कौन सा निष्कर्ष सही है?
If \(A\subseteq U\) and \(A'= \varnothing\), which conclusion is correct?
Explanation opens after your attempt
B. (A=U)
Concept
If the complement is empty, no element of (U) lies outside (A). Therefore (A=U).
Why this answer is correct
The correct answer is B. (A=U). If the complement is empty, no element of (U) lies outside (A). Therefore (A=U).
Exam Tip
पूरक खाली है तो (U) में (A) के बाहर कोई तत्व नहीं है। इसलिए (A=U) होगा।
