Correct Answer

B. (9)

Step 1

Concept

At (e=-1), the \(x^{11}\) term vanishes but the coefficient of \(x^9\) remains (-3). Therefore the degree is (9).

Step 2

Why this answer is correct

The correct answer is B. (9). At (e=-1), the \(x^{11}\) term vanishes but the coefficient of \(x^9\) remains (-3). Therefore the degree is (9).

Step 3

Exam Tip

(e=-1) पर \(x^{11}\) पद हटता है लेकिन \(x^9\) का गुणांक (-3) रहता है। इसलिए डिग्री (9) है।
