Correct Answer

B. यह अपरिमेय है क्योंकि दशमलव असांत और अनावर्ती हैIt is irrational because the decimal is non-terminating and non-recurring

Step 1

Concept

Reappearance of a digit alone is not recurrence unless a fixed block repeats.

Step 2

Why this answer is correct

Here the number of zeros changes, so the decimal is non-recurring.

Step 3

Exam Tip

Identify a non-terminating non-recurring decimal as irrational. चरण 1: केवल एक अंक का बार-बार आना आवर्तन नहीं कहलाता, जब तक निश्चित समूह न दोहराए। चरण 2: यहाँ शून्यों की संख्या बदल रही है, इसलिए दशमलव अनावर्ती है। चरण 3: असांत अनावर्ती दशमलव को अपरिमेय पहचानें।
