Correct Answer

A. यह हमारी परिमेय मान्यता के विरुद्ध है, अतः दी गई संख्या अपरिमेय हैThis contradicts our rational assumption, hence the given number is irrational

Step 1

Concept

In the proof, the rational assumption leads to an impossible common factor.

Step 2

Why this answer is correct

This contradicts the assumption.

Step 3

Exam Tip

So the final line should clearly state contradiction and irrationality. चरण 1: प्रमाण में परिमेय मान्यता से असंभव साझा गुणनखंड मिलता है। चरण 2: यह मान्यता के विरुद्ध है। चरण 3: इसलिए अंतिम पंक्ति में विरोधाभास और अपरिमेयता दोनों स्पष्ट लिखें।
