Correct Answer

A. \(\frac{\sqrt{2}}{2}\)

Step 1

Concept

\(\sqrt{2}\) is irrational, and dividing by non-zero rational (2) keeps it irrational.

Step 2

Why this answer is correct

\(\frac{\sqrt{2}}{2}\) is about (0.707), so it lies between (0) and (1).

Step 3

Exam Tip

Check both the interval condition and the nature of the number. चरण 1: \(\sqrt{2}\) अपरिमेय है और अशून्य परिमेय (2) से भाग देने पर अपरिमेयता बनी रहती है। चरण 2: \(\frac{\sqrt{2}}{2}\) लगभग (0.707) है, इसलिए यह (0) और (1) के बीच है। चरण 3: अंतराल और संख्या की प्रकृति दोनों शर्तें साथ-साथ जाँचें।
