I'd say the correct answer is A, that each couplet must rhyme.
Because B isn't correct, as there may be a specific point of view, depends on the poet.
C again isn't correct, because the meanings aren't always hidden.
And in D, it depends, some poets focus on the form of the poem, whereas they find the content irrelevant, and vice versa.

A claim is a sentence proving your point (or your side of the argument).
Hope this helps!

I think this is a metaphor - by saying “I can fix you” he is saying that he can help the person in need.
