Explanation opens after your attempt
Correct Answer

A. (r) शून्यक है(r) is a zero

Step 1

Concept

Even when the graph touches, (y=0). Therefore the (x)-coordinate (r) of ((r,0)) is a zero.

Step 2

Why this answer is correct

The correct answer is A. (r) शून्यक है / (r) is a zero. Even when the graph touches, (y=0). Therefore the (x)-coordinate (r) of ((r,0)) is a zero.

Step 3

Exam Tip

छूने पर भी (y=0) होता है। इसलिए ((r,0)) का (x)-निर्देशांक (r) शून्यक है।
