Conditional Convergence of Series
Given the series $$S = \displaystyle\sum_{n=1}^{\infty} \frac{(-1)^{n+1}}{n}$$, which of the following series has the same convergence behavior as $$S$$?
I. $$\displaystyle\sum_{n=1}^{\infty} \frac{(-1)^{n+1}}{2n}$$
II. $$\displaystyle\sum_{n=1}^{\infty} \frac{(-1)^{n+1}}{n + \sin(n)}$$
III. $$\displaystyle\sum_{n=1}^{\infty} \frac{(-1)^{n+1}\sqrt{n}}{n^{3/2}}$$
A
$$\text{I and II only}$$
B
$$\text{All three series}$$
C
$$\text{I and III only}$$
D
$$\text{I only}$$
