Second
B, Thanks, Chic
noun, な adjective
If something is the latter, it can't be first, it has to be at least second. This works for lists too. So if you have A through D, it's going to be B.
This word is also used as slang for おつかれさま, which is where the thanks meaning comes from. It can also be used as a prefix to mean chic.
This has the same reading as the kanji you learned, meaning you know the reading!
