Determine whether the series from 0 to infinity of cos(nπ)/(n + 3) converges conditionally or absolutely.

A. The series diverges.
B. The series converges conditionally but not absolutely.
C. The series converges absolutely but not conditionally.
D. The series converges absolutely.

I think the answer is B. (Also, when is C actually possible?)
