Question 1/1 Easy Mathematics Relations and Functions Types of relations Class 12 Level 5

यदि \(A=\{a,b\}\) है, तो पहचान संबंध कौन सा होगा?

If \(A=\{a,b\}\), which one is the identity relation?

Explanation opens after your attempt
Correct Answer

A. ({(a,a),(b,b)})

Step 1

Concept

In the identity relation, each element is related only to itself.

Step 2

Why this answer is correct

For (a) and (b), the diagonal pairs are ((a,a)) and ((b,b)).

Step 3

Exam Tip

Hence the correct relation is ({(a,a),(b,b)}). चरण 1: पहचान संबंध में हर अवयव केवल अपने-आप से संबंधित होता है। चरण 2: (a) और (b) के लिए विकर्ण युग्म ((a,a)) और ((b,b)) हैं। चरण 3: इसलिए सही संबंध ({(a,a),(b,b)}) है।
