Correct Answer
C. ( (2,4) )
Concept
\(2\in[1,3]\) and \(4\in(2,5)\), so \((2,4)\in A\times B\). In exams, check endpoints of closed and open intervals carefully.
Why this answer is correct
The correct answer is C. ( (2,4) ). \(2\in[1,3]\) and \(4\in(2,5)\), so \((2,4)\in A\times B\). In exams, check endpoints of closed and open intervals carefully.
Exam Tip
\(2\in[1,3]\) और \(4\in(2,5)\), इसलिए \((2,4)\in A\times B\)। परीक्षा में बंद और खुले अंतराल के सिरों को ध्यान से देखें।
