Correct Answer

A. (p) सम है, इसलिए (q) भी बिना किसी प्रतिस्थापन के सम है(p) is even, so (q) is also even without any substitution

Step 1

Concept

(p) being even does not automatically make (q) even.

Step 2

Why this answer is correct

To prove (q) even, (p=2k) must be substituted in the original equation.

Step 3

Exam Tip

Writing conclusions without support weakens the proof. चरण 1: (p) सम होने से अपने आप (q) सम नहीं होता। चरण 2: (q) को सम सिद्ध करने के लिए (p=2k) को मूल समीकरण में रखना पड़ता है। चरण 3: बिना आधार के निष्कर्ष लिखना प्रमाण को कमजोर बनाता है।
