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

\[
\frac{7t}{y} dy + (7 \ln y + 2) dt = 0
\]

---

**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 \(F(t,y) = C\) is \( \boxed{\text{ }} \), where \(C\) is an arbitrary constant.  
  (Type an expression using \(t\) and \(y\) as the variables.)
