1. **State the problem:** We need to find the sum of the infinite series $$\sum_{n=1}^\infty \frac{e^n}{\pi^n}$$ or determine if it diverges.
2. **Identify the type of series:** This is a geometric series with the general term $$a_n = \left(\frac{e}{\pi}\right)^n$$.
3. **Recall the formula for the sum of an infinite geometric series:**
$$\text{If } |r| < 1, \quad \sum_{n=1}^\infty ar^{n-1} = \frac{a}{1-r}$$
Since our series starts at $n=1$, the sum is:
$$\sum_{n=1}^\infty r^n = \frac{r}{1-r}$$
where $$r = \frac{e}{\pi}$$.
4. **Check the convergence condition:**
Since $$e \approx 2.718$$ and $$\pi \approx 3.1415$$, we have
$$\left|\frac{e}{\pi}\right| < 1$$
so the series converges.
5. **Calculate the sum:**
$$\sum_{n=1}^\infty \left(\frac{e}{\pi}\right)^n = \frac{\frac{e}{\pi}}{1 - \frac{e}{\pi}} = \frac{\frac{e}{\pi}}{\frac{\pi - e}{\pi}} = \frac{e}{\pi - e}$$
6. **Final answer:** The sum of the series is
$$\boxed{\frac{e}{\pi - e}}$$
which corresponds to choice B.
