Which of the following statements is true?

a) The geometric series Σ∞n=1 r^n is always convergent.

b) for the series Σ∞n=1an, if lim n→∞ an = 1/3, then the series will be convergent.

c) If an> bn for all values of n and Σ∞n=1 bn is convergent, then Σ∞ n=1an is also convergent.

d) None of the above
