यदि \(A=\{1,2,3,4\}\) और \(R=\{(a,b):a=1\}\) है, तो (R) में कितने pairs होंगे?
If \(A=\{1,2,3,4\}\) and \(R=\{(a,b):a=1\}\), how many pairs will be in (R)?
Explanation opens after your attempt
C. (4)
Concept
The first component is fixed as (1), and the second component can take (4) values from (A). Hence there will be (4) pairs.
Why this answer is correct
The correct answer is C. (4). The first component is fixed as (1), and the second component can take (4) values from (A). Hence there will be (4) pairs.
Exam Tip
