Correct Answer

A. जब (r=0)When (r=0)

Step 1

Concept

From (r+s=s), subtract (s) from both sides to get (r=0).

Step 2

Why this answer is correct

(0) is rational, so the condition is possible.

Step 3

Exam Tip

Form a simple equation before judging number types. चरण 1: (r+s=s) से दोनों ओर (s) घटाने पर (r=0) मिलता है। चरण 2: (0) परिमेय है इसलिए स्थिति संभव है। चरण 3: सरल समीकरण बनाकर संख्या के प्रकार की जांच करें।
