Correct Answer

B. जो (x)-अक्ष को एक ही बिंदु पर स्पर्श करेOne that touches the (x)-axis at only one point

Step 1

The correct answer is A. एक बिंदु पर छुएगा / It will touch at one point. One real zero means the graph meets the (x)-axis at only one point. For a parabola, this is usually the touching case.

Step 3

Exam Tip

एक वास्तविक शून्यक का अर्थ है ग्राफ (x)-अक्ष से केवल एक बिंदु पर मिलता है। परवलय में यह सामान्यतः छूने की स्थिति होती है।
