To determine the rhyme scheme of the poem, you would need to analyze how the lines rhyme with each other. However, based on your options, here's a quick clarification:
A. This would indicate a couplet rhyme scheme (AA BB ...). B. This indicates an alternate rhyme scheme (ABAB). C. This indicates a single rhyme for odd lines (A A A ...). D. This indicates that only the first two lines of each stanza rhyme (AA).
Without the actual poem, it's impossible to identify the correct answer definitively. If you have the poem handy, you can identify which of these options applies based on how the lines rhyme.
