Correct Answer

B. घात (4) रहेगीThe degree remains (4)

Step 1

Concept

At (a=5), the \(x^2\) term disappears, but \(2x^4\) remains. Therefore, the degree remains (4).

Step 2

Why this answer is correct

The correct answer is B. घात (4) रहेगी / The degree remains (4). At (a=5), the \(x^2\) term disappears, but \(2x^4\) remains. Therefore, the degree remains (4).

Step 3

Exam Tip

(a=5) पर \(x^2\) पद हटता है, लेकिन \(2x^4\) मौजूद है। इसलिए घात (4) रहेगी।
