Correct Answer

A. नहींNo

Step 1

Concept

((2,1)) and ((1,3)) require ((2,3)), which is present.

Step 2

Why this answer is correct

((1,2)) and ((2,1)) require ((1,1)), and ((2,1)) with ((1,2)) requires ((2,2)). Both are present.

Step 3

Exam Tip

After checking all chains, the relation is actually transitive, so option A is the trap. चरण 1: ((2,1)) और ((1,3)) से ((2,3)) चाहिए, जो मौजूद है। चरण 2: लेकिन ((2,3)) के बाद यदि कोई ((3,c)) नहीं है तो वहां कमी नहीं बनेगी; फिर ((1,2)) और ((2,1)) से ((1,1)) मौजूद है। चरण 3: अब ((2,1)) और ((1,2)) से ((2,2)) भी मौजूद है, इसलिए यहां गलत विकल्प नहीं चुनना चाहिए।
