Find the derivative of the given function. Simplify and express the answer using positive exponents only.

$y=y=(\frac{7-x^5}{x^2}{)}^5$

a$.\frac{5(x^5-7{)}^4(3x^5+14)}{x^{11}}$

b$.-\frac{4(x^5-7{)}^4(3x^5+14)}{x^{11}}$

c$.-\frac{5(x^5-7{)}^4(3x^5+7)}{x^{11}}$

d$.-\frac{5(x^5-7{)}^4(3x^5+14)}{x^{11}}$

e$.\frac{5(x^5-7{)}^4(5x^5+14)}{x^{11}}$
