Rewrite the Expression Without Using Negative Exponents $\frac{9 a^{-3} b^{-8}}{c^{-3} d^{4}}$

Rewrite the expression without using negative exponents. (A ssume all variables represent nonzero real numbers.)
- $\frac{9 a^{-3} b^{-8}}{c^{-3} d^{4}}$

A) $\frac{1}{9 a^{3} b^{8} c^{3} d^{4}}$

B) $\frac{9 c^{3} d^{4}}{a^{3} b^{8}}$

C) $\frac{9 c^{3}}{a^{3} b^{8} d^{4}}$

D) $\frac{c^{3}}{9 a^{3} b^{8} d^{4}}$
