Correct Answer
A. (5) सहप्रांत में है पर परिसर में नहीं(5) is in the codomain but not in the range
Concept
The range is ({2,3,4}), so (5) is not obtained. In exams, every element of the codomain need not be in the range.
Why this answer is correct
The correct answer is A. (5) सहप्रांत में है पर परिसर में नहीं / (5) is in the codomain but not in the range. The range is ({2,3,4}), so (5) is not obtained. In exams, every element of the codomain need not be in the range.
Exam Tip
परिसर ({2,3,4}) है इसलिए (5) प्राप्त नहीं होता। परीक्षा में सहप्रांत का हर तत्व परिसर में हो यह जरूरी नहीं है।
