यदि \(A\cap B'= \varnothing\), तो कौन सा कथन सही है?
If \(A\cap B'=\varnothing\), which statement is correct?
Explanation opens after your attempt
Correct Answer
A. \(A\subseteq B\)
Concept
No element of (A) is in (B'), so every element of (A) must be in (B). Hence \(A\subseteq B\).
Why this answer is correct
The correct answer is A. \(A\subseteq B\). No element of (A) is in (B'), so every element of (A) must be in (B). Hence \(A\subseteq B\).
Exam Tip
(A) का कोई सदस्य (B') में नहीं है, इसलिए (A) का हर सदस्य (B) में होगा। अतः \(A\subseteq B\) है।
