**Determine whether the following series converges. Justify your answer.**

\[
\sum_{k=1}^{\infty} \frac{8^k + 10}{8^k}
\]

---

**Options:**

- **A.** The series is a geometric series with a common ratio \(\frac{1}{8}\). This is less than 1, so the series converges by the properties of a geometric series.
  
- **B.** 

  Because \(\frac{8^k + 10}{8^k} \leq \frac{8^k}{8^k} = 1\) for any positive integer \(k\) and \(\sum_{k=1}^{\infty} \frac{8^k}{8^k} = \sum_{k=1}^{\infty} \frac{1}{1}\) converges, the given series converges by the Comparison Test.

**C.** Because  
\[
\frac{8}{k} < \frac{8}{k} + \frac{10}{k} \text{ for any positive integer } k \text{ and } \sum \frac{8}{k}
\] 
diverges, the given series diverges by the Comparison Test.

**D.** The Ratio Test yields \( r = \_\_\_ \). This is less than 1, so the series converges by the Ratio Test.  
*(Type an exact answer.)*

**E.** The series is a geometric series with common ratio \( \_\_\_ \). This is greater than 1, so the series diverges by the properties of a geometric series.
