Answer and explanationउत्तर और व्याख्या
Correct answer:सही उत्तर: One-oneएकैकी
Step 1: Each element of the domain has exactly one image. Step 2: The images (a,c,d) are distinct. Step 3: In a finite set, if images are not repeated, the function is one-one.चरण 1: प्रांत के हर तत्व का ठीक एक प्रतिबिंब है। चरण 2: प्रतिबिंब (a,c,d) अलग-अलग हैं। चरण 3: सीमित समुच्चय में प्रतिबिंब दोहराए न जाएँ तो फलन एकैकी होता है।
