Correct Answer

A. (1)

Step 1

Concept

At (D=0), both roots are equal, so the number of distinct real roots is (1). Remember the root is repeated.

Step 2

Why this answer is correct

The correct answer is A. (1). At (D=0), both roots are equal, so the number of distinct real roots is (1). Remember the root is repeated.

Step 3

Exam Tip

(D=0) पर दोनों मूल समान होते हैं, इसलिए अलग-अलग वास्तविक मूलों की संख्या (1) है। ध्यान रखें मूल दो बार दोहरता है।
