Solution

The correct option is C $x^{9} + x^{8} + x^{2} + x$
The standard form for writing a polynomial is to put the term with the highest degree first, then the term with the next highest degree, and so on.
$∴ (x^{7} + 1) (x^{2} + x)$ $= x^{9} + x^{8} + x^{2} + x$ is the standard from of the polynomial.
