Correct Answer
A. \([-3,-1]\cup[1,3]\)
Concept
(A=[-3,3]) and (B=(-1,1)). Removing (B) gives \([-3,-1]\cup[1,3]\).
Why this answer is correct
The correct answer is A. \([-3,-1]\cup[1,3]\). (A=[-3,3]) and (B=(-1,1)). Removing (B) gives \([-3,-1]\cup[1,3]\).
Exam Tip
(A=[-3,3]) और (B=(-1,1)) है। (B) हटाने पर \([-3,-1]\cup[1,3]\) मिलता है।
