Correct Answer

A. संक्रमण नहींNot transitive

Step 1

Concept

((3,2)) and ((2,3)) require ((3,3)), which is present.

Step 2

Why this answer is correct

((1,3)) and ((3,2)) require ((1,2)), also present; other self-pair checks do not create a missing pair.

Step 3

Exam Tip

After full checking, the relation is transitive, so saying not transitive is wrong. चरण 1: ((3,2)) और ((2,3)) से ((3,3)) चाहिए, जो मौजूद है। चरण 2: लेकिन ((1,3)) और ((3,2)) से ((1,2)) चाहिए, वह मौजूद है; फिर भी ((1,2)) और ((2,2)) से ((1,2)) ठीक है। सभी मुख्य जोड़ी मौजूद हैं। चरण 3: पूरी जांच के बाद संबंध संक्रमण है, इसलिए संक्रमण नहीं कहना गलत है।
