Correct Answer

B. (q=3r)

Step 1

Concept

From \(q^2=3k^2\), \(q^2\) is divisible by (3).

Step 2

Why this answer is correct

Since (3) is prime, (q) is divisible by (3).

Step 3

Exam Tip

Therefore (q=3r) can be written. चरण 1: \(q^2=3k^2\) से \(q^2\) (3) से विभाज्य है। चरण 2: (3) अभाज्य है, इसलिए (q) (3) से विभाज्य है। चरण 3: इसलिए (q=3r) लिखा जा सकता है।
