Correct Answer
A. यह सममित हैIt is symmetric
Concept
For every \((a,b)\in R\), \((b,a)\in R\) is also present, so (R) is symmetric. In exams, match each pair with its reverse.
Why this answer is correct
The correct answer is A. यह सममित है / It is symmetric. For every \((a,b)\in R\), \((b,a)\in R\) is also present, so (R) is symmetric. In exams, match each pair with its reverse.
Exam Tip
हर \((a,b)\in R\) के साथ \((b,a)\in R\) भी है, इसलिए (R) सममित है। परीक्षा में उल्टे ordered pair को मिलाएं।
