**11.** Verify that the given differential equation is exact; then solve it.

\[
\left( \frac{8x}{y} - \frac{3y^2}{x^4} \right) dx + \left( \frac{2y}{x^3} - \frac{4x^2}{y^2} + \frac{5}{\sqrt{y}} \right) dy = 0
\]

Select the correct choice below and, if necessary, fill in the answer box to complete your choice.

- ☐ A. The equation is exact and an implicit solution in the form \( F(x,y) = C \) is \_\_\_\_\_\_\_\_ = \( C \),
  where \( C \) is an arbitrary constant.
  (Type an expression using \( x \) and \( y \) as the variables.)

- ☐ B. The equation is not exact.
