Explain why $\frac{\sqrt{a}}{\sqrt{b}} = \sqrt{\frac{a}{b}}$. Choose the correct answer below. A. $\frac{\sqrt{a}}{\sqrt{b}} = \frac{a^{-2}}{b^{-2}} = (\frac{a}{b})^{-2} = \sqrt{\frac{a}{b}}$ B. $\frac{\sqrt{a}}{\sqrt{b}} = \frac{a^{\frac{1}{2}}}{b^{\frac{1}{2}}} = (\frac{a}{b})^{\frac{1}{2}} = \sqrt{\frac{a}{b}}$ C. $\frac{\sqrt{a}}{\sqrt{b}} = \frac{a^{-\frac{1}{2}}}{b^{-\frac{1}{2}}} = ab^{-\frac{1}{2}} = \sqrt{\frac{a}{b}}$ D. $\frac{\sqrt{a}}{\sqrt{b}} \neq \sqrt{\frac{a}{b}}$
