यदि (A-B=A) है, तो कौन-सा कथन सही है?
If (A-B=A), which statement is correct?
Explanation opens after your attempt
A. \(A\cap B=\varnothing\)
Concept
Removing (B) does not change (A), so (A) and (B) have no common element. Thus \(A\cap B=\varnothing\).
Why this answer is correct
The correct answer is A. \(A\cap B=\varnothing\). Removing (B) does not change (A), so (A) and (B) have no common element. Thus \(A\cap B=\varnothing\).
Exam Tip
(B) हटाने पर (A) में कोई बदलाव नहीं हुआ, इसलिए (A) और (B) में कोई सामान्य तत्व नहीं है। अतः \(A\cap B=\varnothing\)।
