यदि \(A=\{1,2,3,4,5,6\}\), \(B=\{2,4,6\}\) और \(C=\{1,2,3\}\) है, तो (B-C) क्या है?
If \(A=\{1,2,3,4,5,6\}\), \(B=\{2,4,6\}\), and \(C=\{1,2,3\}\), what is (B-C)?

Correct Answer
A. ( {4,6} )
Concept
The common element (2) is removed from (B), so ({4,6}) remains. Even with three sets, focus on the asked operation.
Why this answer is correct

Exam Tip
(B) में से (C) का समान अवयव (2) हटता है, इसलिए ({4,6}) बचता है। तीसरा समुच्चय होने पर भी चुनी गई क्रिया पर ध्यान दें।
