Correct Answer

A. (3) अभाज्य गुणनखंड बनकर अंश और हर दोनों में पहुँचता है(3) acts as a prime factor that reaches both numerator and denominator

Step 1

Concept

From \(p^2=3q^2\), (3) first appears in (p).

Step 2

Why this answer is correct

Then putting (p=3k) makes (3) appear in (q) too.

Step 3

Exam Tip

This gives a common factor in numerator and denominator. चरण 1: समीकरण \(p^2=3q^2\) से (3) पहले (p) में आता है। चरण 2: फिर (p=3k) रखने से (3) (q) में भी आता है। चरण 3: यही अंश और हर दोनों में साझा गुणनखंड देता है।
