Determine whether the equation is exact. If it is$,$ then solve it$.$

$(3x^{2}y4)dx(x^3-3)dy=0$

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 $q,=C,$ where C is an arbitrary constant.

$($Type an expression using $x$ and $y$ as the variables.$)$

B$.$ The equation is not exact.
