Answer:

Option B. \frac{1}{3x+1}.

Step-by-step explanation:

The given expression is \frac{x+2}{x^{3}+2x^{2}-9x-18}\div \frac{3x+1}{x^{2}-9}

In this expression we will simplify \frac{x+2}{x^{3}+2x^{2}-9x-18} first.

=\frac{x+2}{x^{2}(x+2)-9(x+2)}

=\frac{x+2}{(x+2)(x^{2}-9)}

=\frac{1}{x^{2}-9}

Now we can rewrite the given expression as

=\frac{1}{x^{2}-9}\div \frac{3x+1}{x^{2}-9}

=\frac{1}{x^{2}-9}\times \frac{x^{2}-9}{3x+1}

= \frac{1}{3x+1}

So option B. \frac{1}{3x+1} is the right answer.
