If the degree of \(x^5+ax^3+4\) is (5), what is the correct statement about (a)?
A. (a) कोई भी वास्तविक संख्या हो सकता है(a) can be any real number
\(x^5\) का गुणांक (1) है जो शून्य नहीं है। इसलिए (a) का मान डिग्री (5) को नहीं बदलता। / The coefficient of \(x^5\) is (1), which is non-zero. So the value of (a) does not change degree (5).
