Explanation opens after your attempt
C. \(\varnothing\)
Concept
When (A=B), no element remains in (A) that is not in (B). Therefore, \(A-B=\varnothing\).
Why this answer is correct
The correct answer is C. \(\varnothing\). When (A=B), no element remains in (A) that is not in (B). Therefore, \(A-B=\varnothing\).
Exam Tip
जब (A=B), तो (A) में ऐसा कोई अवयव नहीं बचता जो (B) में न हो। इसलिए \(A-B=\varnothing\)।
