Correct Answer

B. (12)

Step 1

Concept

At (e=5), the \(x^{14}\) term vanishes but the coefficient of \(x^{12}\) remains (8). Therefore the degree is (12).

Step 2

Why this answer is correct

The correct answer is B. (12). At (e=5), the \(x^{14}\) term vanishes but the coefficient of \(x^{12}\) remains (8). Therefore the degree is (12).

Step 3

Exam Tip

(e=5) पर \(x^{14}\) पद हटता है लेकिन \(x^{12}\) का गुणांक (8) रहता है। इसलिए डिग्री (12) है।
