यदि \(A=\{1,2,3\}\) और \(R=\{(1,1),(2,2),(3,3),(1,3)\}\) है, तो (R) reflexive है या नहीं?

If \(A=\{1,2,3\}\) and \(R=\{(1,1),(2,2),(3,3),(1,3)\}\), is (R) reflexive?

Explanation opens after your attempt
Correct Answer

A. हाँYes

Step 1

Concept

All diagonal pairs ( (1,1),(2,2),(3,3) ) are present. The extra pair ( (1,3) ) does not stop reflexivity.

Step 2

Why this answer is correct

The correct answer is A. हाँ / Yes. All diagonal pairs ( (1,1),(2,2),(3,3) ) are present. The extra pair ( (1,3) ) does not stop reflexivity.

Step 3

Exam Tip

सभी diagonal pairs ( (1,1),(2,2),(3,3) ) मौजूद हैं। Extra pair ( (1,3) ) reflexive होने से नहीं रोकता।
