Correct Answer

A. यह दिखाना कि (q) भी (5) से विभाज्य हैTo show that (q) is also divisible by (5)

Step 1

Concept

First, (p) is found divisible by (5).

Step 2

Why this answer is correct

Substituting (p=5k) gives divisibility by (5) for (q) too.

Step 3

Exam Tip

A common factor in both creates the contradiction. चरण 1: पहले (p) (5) से विभाज्य मिलता है। चरण 2: (p=5k) को समीकरण में रखने पर (q) के लिए भी (5) से विभाज्यता मिलती है। चरण 3: दोनों में साझा गुणनखंड मिलना विरोधाभास है।
