Answer:

Option C is the right choice.

Explanation:


\mathrm{Vertical\:asymptotes\:of\:}(x^3-8)/(x^2+9)\:\:=\:\:\mathrm{None}


\mathrm{Vertical\:asymptotes\:of\:rational\:Functions}:

For rational functions, the vertical asymptotes are the undefined points, also known as the zeros of the denominator, of the simplified function.

The given function is true for all
x \in \mathbb{R} and has no undefined points.

Therefore, no vertical asymptotes.
