I would say the correct answer is B. longing.
In this poem, the wife is lamenting because she is separated from her husband - for a very long time. She misses her husband and wants to be reunited with him, so she is definitely not content or blithe about her situation (blithe means happy). She is not confused either - she knows that she wants her husband back.
The correct answer should be informal.
Informal level of language involves the use of slang words, and <em>cool </em>is a slang word, so this sentence cannot be formal by any means. It is also not general due to a slang word being used. Substandard language would mean that it is not grammatically correct, and this sentence is, so this is also incorrect.
