Correct Answer

B. (12)

Step 1

Concept

When \(b\neq-2\), the coefficient of \(x^{12}\) is not zero. Therefore the highest power remains (12).

Step 2

Why this answer is correct

The correct answer is B. (12). When \(b\neq-2\), the coefficient of \(x^{12}\) is not zero. Therefore the highest power remains (12).

Step 3

Exam Tip

\(b\neq-2\) होने पर \(x^{12}\) का गुणांक शून्य नहीं है। इसलिए सबसे बड़ी घात (12) रहेगी।
