Correct Answer

B. (11)

Step 1

Concept

At (e=-4), the \(x^{13}\) term vanishes but the coefficient of \(x^{11}\) remains (-5). Therefore the degree is (11).

Step 2

Why this answer is correct

The correct answer is B. (11). At (e=-4), the \(x^{13}\) term vanishes but the coefficient of \(x^{11}\) remains (-5). Therefore the degree is (11).

Step 3

Exam Tip

(e=-4) पर \(x^{13}\) पद हटता है लेकिन \(x^{11}\) का गुणांक (-5) रहता है। इसलिए डिग्री (11) है।
