B. अप्रतिवर्ती और संक्रमीIrreflexive and transitive
Concept
(a<a) is never true, so it is irreflexive. If (a<b) and (b<c), then (a<c), so it is transitive.
Why this answer is correct
The correct answer is B. अप्रतिवर्ती और संक्रमी / Irreflexive and transitive. (a<a) is never true, so it is irreflexive. If (a<b) and (b<c), then (a<c), so it is transitive.
Exam Tip
(a<a) कभी सत्य नहीं, इसलिए यह अप्रतिवर्ती है। यदि (a<b) और (b<c), तो (a<c), इसलिए यह संक्रमी है।
