Solution

The correct option is C $5$
Given polynomial is $p (x) = x^{3} - 9 x + 3 x^{5}$ .

We know that, the degree of a polynomial is the highest power of any of its variables.

Here, in $p (x) = x^{3} - 9 x + 3 x^{5}$ ,the highest power of variable $x$ is $5$ .

So, the degree is $5$ .

Hence, the degree of $p (x) = x^{3} - 9 x + 3 x^{5}$ is $5$ .
