यदि \(f=\{(1,a),(2,a),(3,b)\}\) है, तो उल्टा संबंध ({(a,1),(a,2),(b,3)}) फलन क्यों नहीं है?
If \(f=\{(1,a),(2,a),(3,b)\}\), why is the reversed relation ({(a,1),(a,2),(b,3)}) not a function?

Why this answer is correct
The correct answer is A. क्योंकि (a) की दो छवियां (1) और (2) हैं / Because (a) has two images (1) and (2). In the reversed relation, (a) as a first component is associated with two different images. In exams, watch repeated second components when reversing.
Exam Tip
उल्टे संबंध में (a) पहले घटक के रूप में दो अलग छवियों से जुड़ता है। परीक्षा में उल्टा करते समय दोहराए दूसरे घटक पर ध्यान दें।
