Correct Answer
A. (x) सम सिद्ध करने के बाद (y) सम सिद्ध करनाAfter proving (x) even, proving (y) even
Concept
Only (x) being even gives no contradiction. The coprime condition breaks only when (y) is also even.
Why this answer is correct
The correct answer is A. (x) सम सिद्ध करने के बाद (y) सम सिद्ध करना / After proving (x) even, proving (y) even. Only (x) being even gives no contradiction. The coprime condition breaks only when (y) is also even.
Exam Tip
सिर्फ (x) सम होना विरोधाभास नहीं देता। (y) भी सम हो तभी सहभाज्य शर्त टूटती है।
