Correct Answer

A. (q) को भी (3) से विभाज्य दिखानाTo show (q) is also divisible by (3)

Step 1

Concept

First (p) is proved divisible by (3).

Step 2

Why this answer is correct

Substituting (p=3k) in the equation gives \(q^2=3k^2\).

Step 3

Exam Tip

This proves (q) is also divisible by (3). चरण 1: पहले (p) (3) से विभाज्य सिद्ध होता है। चरण 2: (p=3k) को समीकरण में रखने पर \(q^2=3k^2\) मिलता है। चरण 3: इससे (q) भी (3) से विभाज्य सिद्ध होता है।
