यदि (R) संक्रमण है और (R) में ((x,x)) तथा ((x,y)) हैं, तो कौन सा निष्कर्ष सही है?

If (R) is transitive and contains ((x,x)) and ((x,y)), which conclusion is correct?

Explanation opens after your attempt
Correct Answer

A. ((x,y)) ही आवश्यक है((x,y)) itself is required

Step 1

Concept

Combining ((x,x)) and ((x,y)), the middle element is (x).

Step 2

Why this answer is correct

Transitivity requires ((x,y)), which is already present.

Step 3

Exam Tip

Do not assume a reverse pair just because a self-pair is present. चरण 1: ((x,x)) और ((x,y)) को जोड़ने पर बीच का तत्व (x) है। चरण 2: संक्रमण के लिए ((x,y)) ही चाहिए, जो पहले से मौजूद है। चरण 3: परावर्ती जैसी जोड़ी से भ्रमित होकर उलटी जोड़ी न मानें।
