Functions

Step 1: Identify the general term of the series. The series is of the form: where the general term can be written as: This is a series involving terms that are related to the exponential series, particularly the series for .
Step 2: Recognize the sum. This series can be related to an exponential series and converges to a known value. By analyzing the sum and recognizing the pattern, we find that it evaluates to: Thus, the correct answer is:
