Correct Answer
A. ( {2,3,5,7} )
Concept
\(A=\{2,3,4,5,6,7\}\), and removing (4,6) gives ({2,3,5,7}). First list elements according to the bounds.
Why this answer is correct
The correct answer is A. ( {2,3,5,7} ). \(A=\{2,3,4,5,6,7\}\), and removing (4,6) gives ({2,3,5,7}). First list elements according to the bounds.
Exam Tip
\(A=\{2,3,4,5,6,7\}\) है और (4,6) हटाने पर ({2,3,5,7}) बचता है। पहले सीमा के अनुसार अवयव लिखें।
