Questiona) Use the Quotient Rule to find the derivative of the given function. b) Find the derivative by dividing the expressions first. $$y=\frac{x^{6}}{x^{4}} \text { for } x \neq 0$$ a) Use the Quotient Rule to find the derivative of the given function. Select the correct answer below and fill in the answer box(es) to complete your choice. A. The derivative is $\frac{x^{6} \cdot(\square)+x^{4}(\square)}{x^{8}}$ B. The derivative is $\frac{x^{6} \cdot(\square)-x^{4}(\square)}{x^{6}}$. C. The derivative is $\frac{x^{4} \cdot(\square)-x^{6}(\square)}{x^{8}}$. D. The derivative is $\frac{x^{4} \cdot(\square)-x^{6}(\square)}{x^{6}}$
