Explanation opens after your attempt
Correct Answer
A. \(A\cap B=\varnothing\)
Concept
Every element of (A) is in the complement of (B), so (A) and (B) have no common element. Being in a complement means being outside the set.
Why this answer is correct
The correct answer is A. \(A\cap B=\varnothing\). Every element of (A) is in the complement of (B), so (A) and (B) have no common element. Being in a complement means being outside the set.
Exam Tip
(A) का हर तत्व (B) के पूरक में है, इसलिए (A) और (B) में साझा तत्व नहीं है। पूरक में होने का अर्थ बाहर होना है।
