Explanation opens after your attempt
Correct Answer
A. प्रतिवर्ती और सममितReflexive and symmetric
Concept
It is reflexive because ((1,1),(2,2),(3,3)) are present, and symmetric because the reverse of ((1,2)) is ((2,1)). Hence it satisfies both.
Why this answer is correct
The correct answer is A. प्रतिवर्ती और सममित / Reflexive and symmetric. It is reflexive because ((1,1),(2,2),(3,3)) are present, and symmetric because the reverse of ((1,2)) is ((2,1)). Hence it satisfies both.
Exam Tip
((1,1),(2,2),(3,3)) हैं इसलिए यह प्रतिवर्ती है और ((1,2)) का उल्टा ((2,1)) भी है। इसलिए यह सममित भी है।
