The best choice that analyzes the effect of a type of rhyme used in the stanza is:
• The eye rhyme in lines 3 and 4 causes the lines to have a musical sound that calms the reader.
Eye rhyme refers to words that look similar but do not sound the same when pronounced (in this case, "eye" and "symmetry"). This can create a subtle harmony that contributes to the overall musicality of the poem, enhancing its calming effect on the reader.
